I need to capture requests to folders that aren't file folders to be redirected to a default page with the requested path as the querystring.
For example, if the user requests
www.mysite.com/IT
I want it to redirect to
www.mysite.com/default.aspx?q=IT
However, if they request a page that is in a real sub-folder, that shouldn't be redirected. For example, requests to www.mysite.com/projects/new.aspx shouldn't try to do any re-directions as it's a physical folder and file in the site.
Use the IIS Rewrite module and the set it up in the web.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<clear />
<rule name="Redirector" patternSyntax="Wildcard">
<match url="*" />
<conditions>
<add input="{PATH_INFO}" pattern="/*" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="/default.aspx?q={PATH_INFO}" appendQueryString="true" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
You could define a 404 error page that would redirect to your default page with the "q=" that you desire
