I've run into an issue with the umbracoUseDirectoryUrls which I hope someone can shed some light on :)

I have a 4.0.2.1 site with a products directory:

HOME
- Products
-- Product1

I set an umbracoURLAlias for Product1 so you can get to it directly eg

website/product1.aspx will bring up website/products/product1.aspx

This works with no issues.

I've been asked if it's possible to have it extensionless so I've enabled umbracoUseDirectoryUrls as described here: http://our.umbraco.org/wiki/install-and-setup/setting-up-umbraco-for-friendly-urls

This works fine on a test server (win2003).

website/product1 ---> website/products/product1.aspx

However on the production server (also win2003) something odd happens:

website/product1 ---> website/products_product1.asp

The servers look to be set up the same but I'm not sure why the production is defaulting to ".asp" and why the directory "/" is being made into "_"

Any ideas?

Thanks in advance!
