Htaccess rewrite append query string

Environment variables can then be used in a variety of contexts, including CGI programs, other RewriteRule directives, or CustomLog directives. Most commonly this will happen if one of the rules causes a redirect - either internal or external - causing the request process to start over.

If the target URI has a htaccess rewrite append query string string, the default behavior will be observed - that is, the original query string will be discarded and replaced with the query string in the RewriteRule target URI.

Use this flag to achieve a more powerful implementation of the ProxyPass directive, to map remote content into the namespace of the local server. Cookies of that kind are forbidden by the cookie security model.

It must be at least two parts separated by a dot. Using the [END] flag terminates not only the current round of rewrite processing like [L] but also prevents any subsequent rewrite processing from occurring in per-directory htaccess context. The example shown here will replace A with B everywhere in a request, and will continue doing so until there are no more As to be replaced.

While the same behavior can be accomplished using the Deny directive, this allows more flexibility in assigning a Forbidden status. This does not apply to new requests resulting from external redirects.

If not, you will get an error from the proxy module. You can use this to make pseudo if-then-else constructs: Then, that environment variable is used to exclude those requests from the access log. G gone The [G] flag forces the server to return a Gone status with the response.

Does the file exist? For example, one might use this to force all files without a file extension to be parsed by the php handler: Lifetime The time for which the cookie will persist, in minutes. Use this flag to exclude problematic rules. Be willing to replace 1 character in each pass of the loop RewriteRule ".

Using the [NE] flag prevents that from happening. Security Warning Take care when constructing the target URL of the rule, considering the security impact from allowing the client influence over the set of URLs to which your server will act as a proxy.

The example given here will rewrite any request to index. That is, if the rule matches, then it is processed as usual and control moves on to the next rule. Is the request for a non-existent file?

RewriteRule Flags

This can be thought of as a goto statement in your rewrite ruleset. To decide whether or not to use this rule: For example, if you wanted all image requests to be handled by a back-end image server, you might do something like the following: On subrequests, it is not always useful, and can even cause errors, if the complete set of rules are applied.

Using the short form you can set the environment variable named VAR to an empty value. You may optionally also set the following values: While this pattern still matches i.

If no query string is used in the substitution, a question mark can be appended to it in combination with this flag. The following rule will forbid. It is set to expire in minutes 24 hours and is returned for all URIs. You will almost always want to use [R] in conjunction with [L] that is, use [R,L] because on its own, the [R] flag prepends http: Flags are included in square brackets at the end of the rule, and multiple flags are separated by commas.

This technique is offered as an example, not as a recommendation. JPG files are both acceptable, for example. Domain The domain for which you want the cookie to be valid. B escape backreferences The [B] flag instructs RewriteRule to escape non-alphanumeric characters before applying the transformation.

Consider the following rule: RewriteRule "oldproduct" "-" [G,NC] When using [G], an [L] is implied - that is, the response is returned immediately, and no further rules are evaluated.

Using the B flag, non-alphanumeric characters in backreferences will be escaped. When using [F], an [L] is implied - that is, the response is returned immediately, and no further rules are evaluated.

For example, a page which is included using an SSI Server Side Include is a subrequest, and you may want to avoid rewrites happening on those subrequests.BNP|backrefnoplus (don't escape space to +) The [BNP] flag instructs RewriteRule to escape the space character in a backreference to %20 rather than '+'.

Useful when the backreference will be used in the path component rather than the query string.
