Full stop / period in URL breaks extensionless URL ... but only on release

Developing an application using MVC-style extensionless URL's. One of the pages has a url that sometimes contains an email address. On my local machine this works fine. However when I publish to the test server, trying to access this URL yields a 404 error, unless you take the full stop out, in which case it routes as expected开发者_StackOverflow中文版.

I've tried adding this to the web.config file:

    <httpRuntime relaxedUrlToFileSystemMapping="true"/>

But it has no effect

Any ideas what might be causing this? Even if I could find a more helpful error than just a 404 it'd be a start!

Cheers, Matt

I've been banging my head against a wall with this today too - I found the answer was to add a trailing slash to the call.

First thanks as your question set me looking at something that it was on my todo list to solve for myself. Second, while I was looking at that, I came across the requestPathInvalidChars attribute of the httpRuntime config element which looks like it should be what you want here (and what I want elsewhere).
