Intermittently we see on a server the error
Request format is unrecognized for URL unexpectedly ending in /methodname
All solutions I have found for this error gives the same answer, which is what is answered in i.e. this question: Request format is unrecognized for URL unexpectedly ending in
The big problem for me here is that my web.config file already includes the necessary info:
<system.web>
<webServices>
<protocols>
<add name="HttpGet" />
<add name="HttpPost" />
</protocols>
</webServices>
</system.web>
And it obviously works as the webservice can be called just fine, until it suddenly fails for no apparent reason. Restarting the webservice (by forcing a web.config change) or even restarting the computer always brings the service back up, until it fails again a day or two later.
What can cause this error, appart from the HttpGet/HttpPost settings?
