This article provides an overview of the URL Rewrite Module and explains the configuration concepts that are used by the module. While the primary purpose of the module is to rewrite request URLs to more friendly URLs, you can also use the module to define rules that perform redirects, send custom responses, or abort requests. Rewrite Rules Overview A rewrite rule defines the logic of what to compare or match the request URL with, and what to do if the comparison is successful.
Prefix Substitution with http: If you want to use other response codes in the range just specify them as a number or use one of the following symbolic names: Use it for rules which should canonicalize the URL and give it back to the client, e. When you use this flag, make sure that the substitution field is a valid URL!
If not, you are redirecting to an invalid location!
And remember that this flag itself only prefixes the URL with http: Usually you also want to stop and do the redirection immediately. Use this flag to mark pages which no longer exist as gone. P Proxy This flag forces the substitution part to be internally forced as a proxy request and immediately i.
You have to make sure that the substitution string is a valid URI e. If not you get an error from the proxy module. Use this flag to achieve a more powerful implementation of the ProxyPass directive, to map some remote stuff into the namespace of the local server.
To use this functionality make sure you have the proxy module compiled into your Apache server program. This corresponds to the Perl last command or the break command from the C language. Use this flag to prevent the currently rewritten URL from being rewritten further by following rules.
This corresponds to the Perl next command or the continue command from the C language. Use this flag to restart the rewriting process, i. But be careful not to create an infinite loop! C Chain This flag chains the current rule with the next rule which itself can be chained with the following rule, etc.
This has the following effect: If the rule does not match, then all following chained rules are skipped.
NS Skip if internal sub-request This flag forces the rewriting engine to skip a rewriting rule if the current request is an internal sub-request.
On sub-requests it is not always useful and even sometimes causes a failure to if the complete set of rules are applied. Use this flag to exclude some rules. Use the following rule for your decision: In these cases, use this flag. NC Case insensitive This makes the Pattern case-insensitive, i.
QSA Append query string This flag forces the rewriting engine to append a query string part in the substitution string to the existing one instead of replacing it. Use this when you want to add more data to the query string via a rewrite rule. This flag is just a hack to be able to post-process the output of RewriteRule directives by Alias, ScriptAlias, Redirect, etc.
A trivial example to show the semantics: You have to use this flag if you want to intermix directives of different modules which contain URL-to-filename translators. Use this to make pseudo if-then-else constructs: You can use this flag more than once to set more than one variable.
Use this to strip but remember information from URLs.Google Page-Speed: Don't include a query string in the URL for static resources. Most proxies, most notably Squid up through version , do not cache resources with a "?".

The order of rules in the ruleset is important because the rewriting engine processes them in a special (and not very obvious) order.
The rule is this: The rewriting engine loops through the ruleset rule by rule (RewriteRule directives) and when a particular rule matches it optionally loops through existing corresponding conditions (RewriteCond directives).
