I found the need to be able to call my .Net WebService using HTTP Get. Usually all you have to do to get this to work is use the following format:
[webservice asmxlocation]/[functionname]?[parameters]
When i did this i was getting a "Request format is unrecognized for URL unexpectedly ending in '/functioname' " error. It's been a long time since i've had to use HTTP Get for a webservice. You need to add the following into your web.config file to enable the appropriate protocol:
<webServices>
<protocols>
<add name="HttpGet" />
<add name="HttpPost" />
protocols>
webServices>
