I am having a problem with the URL rewrite module. I have a subdomain with it's own set of rewrite rules and I am getting 404 errors whenever I click on Urls that have been reformatted. My setup is below. On the main site I am using the following inbound rule to rewrite requests from http://mydomain.com/subdomain to http://subdomain.mydomain.com. <rule name="Redirect to Sub Domain" stopProcessing="false"> <match url=".*" /> <conditions> <add input="{HTTP_HOST}" pattern="^subdomain.mydomain.com$" /> <add input="{PATH_INFO}" pattern="^/subdomain/" negate="true" /> </conditions> <action type="Rewrite" url="/subdomain/{R:0}" logRewrittenUrl="false" /> </rule> This resolves fine and works fine. All direct links to other pages on the subdomain render fine. For example http://subdomain.mydomain.com/Page1.aspx works. Now, in my subdomain I an using an outbound rule to change the rewritten URLs to remove the subdomain folder from the link. <rule name="Clean up outbound URLs" preCondition="is text or html"> <match filterByTags="A, Form, Img, Link" pattern="^(?:subdomain|(.*//[_a-zA-Z0-9-\.]*)?/subdomain)(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> <preConditions> <preCondition name="is text or html"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" /> </preCondition> </preConditions> This also works as expected. All links on the pages are rewrittne to remove the subdomain. Links that are written as http://subdomain.mydomain.com/subdomain/Page1.apsx are properly changed to http://subdomain.mydomain.com/Page1.aspx. These pages will render properly when the link is clicked. So, this brings me to the problem. I have additional rewrite rules for the subdomain to resolve product pages from product.aspx?pid=123&uid=1 to /products/123/1. Here is one of those rules. <rule name="Product Details Rewrite Rule" stopProcessing="true"> <match url="^products/([^/]+)/([^/]+)/?$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="Products.aspx?pid={R:1}&uid={R:2}" appendQueryString="false" /> </rule> So after the outbound rewrite rule I am left with a url on Page1.aspx that looks like http://subdomain.domain.com/products/123/1. This is exactly what I want. The problem is when I click on the link it give a 404 error with the following details. -- HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. Requested URL: http://subdomain.mydomain.com/subdomain/products/123/1 -- The error leads me to belive that the clicked url was not passed back into the url rewriter and resolved properly. I have FRT turned on but am not getting anything logged when this happens. Can anyone tell me why I am seeing a 404 error and not my products page?
