ASPX WebRequest Rewriter


Fed up with IIS not providing permalinks? Don’t have access to the IIS control panel on your host? Then wp-aspxrewriter is for you!

Allowing URLS such as: this is the easiest way to enable completely pretty permalinks on IIS 6 or IIS 7.


  • wp-aspxrewriter in action


The plugin consists of two components:

  1. A standard WordPress plugin.
  2. An ASP.NET HttpModule.

To install:

  1. Upload the wp-aspxrewriter folder to the /wp-content/plugins/ directory
  2. Upload the URLRewriteModule to your IIS /bin/ directory
  3. If you are using WordPress 2.3 or 2.4, modify your source code to contain the additional hook that is implemented at that will feature in 2.5. Hint: it’s in function get_pagenum_link.
  4. Activate the plugin through the ‘Plugins’ menu in WordPress
  5. Create your desired permalink structure on Options -> Permalinks, ensuring that it ends with .aspx.

eg. /%year%/%monthnum%/%day%/%post_id%/%postname%.aspx

Recommended bases are:

/word-category /word-tag

  1. Navigate to Manage -> ASPX Rewriter in the admin control panel and copy the setup that is shown
  2. Modify or create a web.config file that contains the following under <configuration>:

replacing all the values in <RewriterRules> with the configuration generated by you in stage 6.

Add the following line to

  1. Add the following to your web.config under <system.web>:

IIS7: <system.webServer>



  1. Try it out!


How does it work?

That depends on which version of IIS you are using.

In IIS 6 without Integrated Pipeline mode, the request comes in, is matched by the engine which then makes a web request to the correct php page. In IIS 7 proper path rewriting is done and the PHP handler is invoked by IIS.

It doesn’t work with my plugin!

Get in touch and I’ll see what I can do to fix it. This is an early release and has worked in the situations I’ve tested, I can’t guarantee it will in all circumstances.
