URL rewriting creates an abstraction between resource locations and their addresses so that the locations and addresses are not tightly linked. The modified rule will then look as follows: This module allows us to rewrite URLs in a cleaner fashion, translating human-readable paths into code-friendly query strings or redirecting URLs based on additional conditions.
The second part contains two more in-depth examples of commonly-used rewrite rules. For more information, see RFC Add new RedirectImageRequests ". The RewriteCond directive lets us add conditions to our rewrite rules to control when the rules will be processed.
The RewriteRule on the final line will come into effect only for requests to non-existent files or directories. This allows you to apply rules based on all sorts of request parameters, including browser identifiers, referring URL or a multitude of other strings. The [QSA] flags are commonly used in rewrite rules.
This example is also future proof, allowing mutliple items and seasons to be correctly rewritten using a single rule.
Extension and options Establish your URL rewrite and redirect rules by creating an instance of the RewriteOptions class with extension methods for each of your rules.
The rule is intended to only redirect requests missing the "www" URL portion, though, and the condition preceding the rule ensures that this happens. However, in this simple example, the performance increase will be negligible.
The application may use the query string information to build the right page for the visitor. And we can do that relatively simply, with the following rule: Additionally, setting rules in.

By default, Apache prohibits using an. Variables are of the following format: Use the [NE] flag on the RewriteRule. Splitting request processing across different apps or across areas of one app. We just rewrite the name to its basename and test for existence of the new extension.
All RewriteConds abide by the following format: You now have an operational. The above will convert, for example, http: Without the condition, this rule would create a loop, with every request matching that rule and being sent back to itself.
Where feasible, you should limit the number and complexity of rules. To make the rule more generic, we can use regular expressions to match parts of the original address and use those parts in a substitution pattern.
We have to make sure that we forbid access only to the particular robot, i. Our example uses a few characters with special meaning: Multiple RewriteCond may be used one after another and, with default behaviour, all must evaluate to true for the following rule to be considered.Apache is the easiest system to get URL rewriting running on.
It usually comes with its own built-in URL rewriting module, mod_rewrite, enabled, and working with mod_rewrite is as simple as uploading correctly formatted and named text files.
