Where is mod rewrite apache

If a RewriteCond evaluates to true, the RewriteRule immediately following will be considered. Multiple RewriteCond may be used one after another and, with default behaviour, all must evaluate to true for the following rule to be considered.

This can be achieved with following conditions rules:. The RewriteRule on the final line will come into effect only for requests to non-existent files or directories. In this tutorial, you learned how to use the RewriteRule directive to redirect URLs, including ones with query strings.

The RewriteCond directive defines a rule condition. One or more RewriteCond can precede a RewriteRule directive. The following rule is then only used if both the current state of the URI matches its pattern, and if these conditions are met. TestString is a string which can contain the following expanded constructs in addition to plain text:. Most are documented here or elsewhere in the Manual or in the CGI specification.

HTTP headers referenced in the expression will be added to the Vary header if the novary flag is not given. If a substitution occurred and the rewriting continues, the value of both variables will be updated accordingly. If used in per-server context i. If a HTTP header is used in a condition this header is added to the Vary header of the response in case the condition evaluates to true for the request.

It is not added if the condition evaluates to false for the request. It has to be kept in mind that conditions follow a short circuit logic in the case of the ' ornext OR ' flag so that certain conditions might not be evaluated at all. CondPattern is the condition pattern, a regular expression which is applied to the current instance of the TestString. TestString is first evaluated, before being matched against CondPattern. CondPattern is usually a perl compatible regular expression , but there is additional syntax available to perform other useful tests against the Teststring :.

Is existing URL, via subrequest. Checks whether or not TestString is a valid URL, accessible via all the server's currently-configured access controls for that path. This uses an internal subrequest to do the check, so use it with care - it can impact your server's performance! This flag only returns information about things like access control, authentication, and authorization.

This flag does not return information about the status code the configured handler static file, CGI, proxy, etc. You can also set special flags for CondPattern by appending [ flags ] as the third argument to the RewriteCond directive, where flags is a comma-separated list of any of the following flags:.

Explanation: If you use a browser which identifies itself as a mobile browser note that the example is incomplete, as there are many other mobile platforms , the mobile version of the homepage is served. Otherwise, the standard page is served. The RewriteEngine directive enables or disables the runtime rewriting engine.

If it is set to off this module does no runtime processing at all. Use this directive to disable rules in a particular context, rather than commenting out all the RewriteRule directives. Note that rewrite configurations are not inherited by virtual hosts. This means that you need to have a RewriteEngine on directive for each virtual host in which you wish to use rewrite rules. RewriteMap directives of the type prg are not started during server initialization if they're defined in a context that does not have RewriteEngine set to on.

The source of this lookup can be of various types. The MapName is the name of the map and will be used to specify a mapping-function for the substitution strings of a rewriting rule via one of the following constructs:.

When such a construct occurs, the map MapName is consulted and the key LookupKey is looked-up. If the key is found, the map-function construct is substituted by SubstValue.

If the key is not found then it is substituted by DefaultValue or by the empty string if no DefaultValue was specified. Empty values behave as if the key was absent, therefore it is not possible to distinguish between empty-valued keys and absent keys. You would then be able to use this map in a RewriteRule as follows:. See the Using RewriteMap for more information. Further details, and numerous examples, may be found in the RewriteMap HowTo.

The RewriteOptions directive sets some special options for the current per-server or per-directory configuration. The Option string can currently only be one of the following:. This forces the current configuration to inherit the configuration of the parent. Make sure the line:. Old thread, just want to put that don't set AllowOverride to all instead use specific mod you want to use,. Make sure this isn't happening to you:. Change the log location to suit your system.

Once your problem is fixed, turn the RewriteLogLevel back down and celebrate. I can't recommend this enough. Good luck in your troubleshooting! Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow.
