Hey Patrickc - thanks!!!
With the help of my tech buddy, and your advice, we did the following to make Search Engine Friendly URL's work in IIS (free). I don't know IIS but these are the steps I remember my mate taking:
1. Install URL Rewrite Module onto server (we have remote access and control over a virtual private server)
2. Once installed, follow these instructions: http://www.iis.net/learn/extensions/url-rewrite-module/importing-apache-modrewrite-rules
- I seem to remember my mate skipping straight to the 'Convert mod_rewrite Rules' instructions - but don't quote me on that!
3. Import the MODX .htaccess file. The MODX .htaccess file has most of the stuff commented out by default. We left it that way as we were only concerned with the 'friendly url' part of it, which is not commented out by default.
4. Note: URL Rewrite didn't successfully import the 'URL base' segment, (whatever that is) but we simply commented it out on the actual user interface of URL Rewrite and finished the import
> Then in MODX site settings, we enabled 'friendly URL's' and 'strict friendly URL's'
> Finaly in each MODX resource that you have, fill in the 'resource alias' field with whatever u want the URL to look like.
Seems to work so far, and forms are processing OK
