Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign hpw. Connect and rewritd knowledge within a what are orange mobile magic numbers location that is structured and easy to search.

So I tried rewrrite this line to the location block above:. Any redirect to localhost doesn't make sense from a remote system e. So the rewrite flags permanent or redirect are not usable in your case. Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect. No need for an explicit rewrite directive. You should not use localhost because you are urk on the fact hiw application is running on a server with a hosts file. There is nothing stating that you must have this hosts files.

It's just very common to have one. Having a loopback rewritr is again another common thing to depend on but you are still dependent on the loopback interface on the networking stack.

It's a rare case to not have these two. If you ever worry about this. This will eliminate the need to for the network stack to reach the localhost. Use caution with this approach as there are a few factors that will come into place on the host OS.

I have never used CodeIgniter before, let alone ANY php framework and I thought I would give it a try. Everything is going fine except I cannot seem to remove the lovedatingfind.com from the URL and still a. mod_rewrite is a way to rewrite the internal request handling. When the web server receives a request for the URL /foo/bar, you can rewrite that URL into something else before the web server will look for a file on disk to match it. Simple example. Nov 27,  · rewrite_lovedatingfind.com is the schema doc for URL Rewrite. Regarding the poorly formed regular expressions: your first example is just more permissive. For example, ^lovedatingfind.com$ will match exampleXcom too, but since it wouldn't exist in the real world in HTTP_HOST (unless you use host headers), it's not a problem to use either. or \. for the value.

Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as when wikipedia. A user might mistype a URL. Organizations often register these "misspelled" domains and redirect them to the "correct" location.

This technique is often used to "reserve" other top-level domains TLD with the same name, or make it easier for a ". The same applies to search engines. By using a "moved permanently" redirect to the new URL, visitors will still end up at the correct page.

Also, in the next search engine pass, the search engine should detect and use the newer URL. The access logs of most web servers keep detailed information about where visitors came from and how they browsed the hosted site.

They do not, however, log which links visitors left by. This is because the visitor's browser has no need to communicate with the original server when the visitor clicks on an outgoing link. This information can be captured in several ways. One way involves URL redirection. Instead of sending the visitor straight to the other site, links on the site can direct to a URL on the original website's domain that automatically redirects to the real target.

This technique bears the downside of the delay caused by the additional request to the original website's server. As this added request will leave a trace in the server log, revealing exactly which link was followed, it can also be a privacy issue.

In such scenarios, displaying the warning causes an additional delay. Web applications often include lengthy descriptive attributes in their URLs which represent data hierarchies, command structures, transaction paths and session information. This practice results in a URL that is aesthetically unpleasant and difficult to remember, and which may not fit within the size limitations of microblogging sites.

URL shortening services provide a solution to this problem by redirecting a user to a longer URL from a shorter one. Sometimes the URL of a page changes even though the content stays the same. Therefore, URL redirection can help users who have bookmarks. This is routinely done on Wikipedia whenever a page is renamed. Redirects can be effectively used for targeting purposes like geotargeting. Device targeting has become increasingly important with the rise of mobile clients.

There are two approaches to serve mobile users: Make the website responsive or redirect to a mobile website version. If a mobile website version is offered, users with mobile clients will be automatically forwarded to the corresponding mobile content. For device targeting, client-side redirects or non-cacheable server-side redirects are used.

Geotargeting is the approach to offer localized content and automatically forward the user to a localized version of the requested URL. Usually server-side redirects are used for Geotargeting but client-side redirects might be an option as well, depending on requirements. Redirects have been used to manipulate search engines with unethical intentions, e. The goal of misleading redirects is to drive search traffic to landing pages, which do not have enough ranking power on their own or which are only remotely or not at all related to the search target.

The approach requires a rank for a range of search terms with a number of URLs that would utilize sneaky redirects to forward the searcher to the target page. This method had a revival with the uprise of mobile devices and device targeting. URL hijacking is an off-domain redirect technique [3] that exploited the nature of the search engine's handling for temporary redirects. If a temporary redirect is encountered, search engines have to decide whether they assign the ranking value to the URL that initializes the redirect or to the redirect target URL.

The URL that initiates the redirect may be kept to show up in search results, as the redirect indicates a temporary nature. Under certain circumstances it was possible to exploit this behavior by applying temporary redirects to well-ranking URLs, leading to a replacement of the original URL in search results by the URL that initialized the redirect, therefore "stealing" the ranking.

This method was usually combined with sneaky redirects to re-target the user stream from the search results to a target page. Search engines have developed efficient technologies to detect these kinds of manipulative approaches. Major search engines usually apply harsh ranking penalties on sites that get caught applying techniques like these.

URL redirection is sometimes used as a part of phishing attacks that confuse visitors about which web site they are visiting. However, redirects can also take you to sites that will otherwise attempt to attack in other ways. For example, a redirect might take a user to a site that would attempt to trick them into downloading antivirus software and installing a Trojan of some sort instead. When a link is clicked, the browser sends along in the HTTP request a field called referer which indicates the source of the link.

This field is populated with the URL of the current web page, and will end up in the logs of the server serving the external link. This technique also eliminates other potentially sensitive information from the referrer URL, such as the session ID , and can reduce the chance of phishing by indicating to the end user that they passed a clear gateway to another site.

Several different kinds of response to the browser will result in a redirection. The techniques used typically depend on the role of the person implementing it and their access to different parts of the system. For example, a web author with no control over the headers might use a Refresh meta tag whereas a web server administrator redirecting all pages on a site is more likely to use server configuration.

The simplest technique is to ask the visitor to follow a link to the new page, usually using an HTML anchor like:. This method is often used as a fall-back — if the browser does not support the automatic redirect, the visitor can still reach the target document by following the link.

In the HTTP protocol used by the World Wide Web , a redirect is a response with a status code beginning with 3 that causes a browser to display a different page. If a client encounters a redirect, it needs to make a number of decisions how to handle the redirect. Different status codes are used by clients to understand the purpose of the redirect, how to handle caching and which request method to use for the subsequent request.

The multiple choices will usually list all choices in the body of the message and show the default choice in the Location: header. Status codes not modified and use proxy are not redirects.

A HTTP response with the "moved permanently" redirect looks like this:. The same is usually true even for programmers writing CGI scripts, though some servers allow scripts to add custom headers e. Many web servers will generate a 3xx status code if a script outputs a "Location:" header line. For example, in PHP , one can use the "header" function:. More headers may be required to prevent caching. This may not fit easily with the natural flow of control through the code. To help with this, some frameworks for server-side content generation can buffer the body data.

In the ASP scripting language, this can also be accomplished using response. Typical configuration directives look like:.

Such configuration can be applied to one or all sites on the server through the server configuration files or to a single content directory through a.

Nginx has an integrated http rewrite module, [10] which can be used to perform advanced URL processing and even web-page generation with the return directive. A showing example of such advanced use of the rewrite module is mdoc.

Netscape introduced the meta refresh feature which refreshes a page after a certain amount of time. This can specify a new URL to replace one page with another. This is supported by most web browsers. This is treated like a permanent redirect by Google, allowing transfer of PageRank to the target page. This technique can be used by web authors because the meta tag is contained inside the document itself.

The meta tag must be placed in the "head" section of the HTML file. The number "0" in this example may be replaced by another number to achieve a delay of that many seconds. The anchor in the "body" section is for users whose browsers do not support this feature. This response is easier to generate by CGI programs because one does not need to change the default status code.

The W3C discourage the use of meta refresh, since it does not communicate any information about either the original or new resource, to the browser or search engine. JavaScript can cause a redirect by setting the window.

It can cause redirect loops when users hit the back button. With the following command you can prevent this type of behaviour.

However, HTTP headers or the refresh meta tag may be preferred for security reasons and because JavaScript will not be executed by some browsers and many web crawlers. One main difference to the above redirect methods is that for a frame redirect, the browser displays the URL of the frame document and not the URL of the target page in the URL bar. This cloaking technique may be used so that the reader sees a more memorable URL or to fraudulently conceal a phishing site as part of website spoofing.

One redirect may lead to another. This is unavoidable if the different links in the chain are served by different servers though it should be minimised by rewriting the URL as much as possible on the server before returning it to the browser as a redirect. Sometimes a mistake can cause a page to end up redirecting back to itself, possibly via other pages, leading to an infinite sequence of redirects. Browsers should stop redirecting after a certain number of hops and display an error message.

Note: An earlier version of this specification recommended a maximum of five redirections [RFC ], Section Content developers need to be aware that some clients might implement such a fixed limitation.

Note that the URLs in the sequence might not repeat, e. There exist services that can perform URL redirection on demand, with no need for technical work or access to the web server your site is hosted on. A redirect service is an information management system, which provides an internet link that redirects users to the desired content. The typical benefit to the user is the use of a memorable domain name, and a reduction in the length of the URL or web address.

A redirecting link can also be used as a permanent address for content that frequently changes hosts, similarly to the Domain Name System. Hyperlinks involving URL redirection services are frequently used in spam messages directed at blogs and wikis. Thus, one way to reduce spam is to reject all edits and comments containing hyperlinks to known URL redirection services; however, this will also remove legitimate edits and comments and may not be an effective method to reduce spam. A major drawback of some URL redirection services is the use of delay pages, or frame based advertising, to generate revenue.

The first redirect services took advantage of top-level domains TLD such as ".
