HTTP 400 Status code when trying to access the service.

Posted by Anonymus under WCF on 11/6/2012 | Points: 10 | Views : 2008 | Status : [Member] | Replies : 1
Hi,

As a part of load testing we are doing this experiment. With the help of a mozilla add on Poster we are trying to hit my WCF service..However, after certain requests I start receiving error message : "unable to access the following endpoint(s)" error.
When I checked the IIS log I found that the status code is 400.

Are there any limitations in using Mozilla Firefox addon "Poster" for doing load testing?

Can any one please help me to understand how to fix this?


Awaiting your favourable response.

Regards,
Anonymus

WCF does not return/show lot of information about what's actually wrong in its side (sad). Try configuring WCF Tracing and see if it helps.

400 - Bad request.
401 - Access denied. IIS defines several different 401 errors that indicate a more specific cause of the error. These specific error codes are displayed in the browser but are not displayed in the IIS log:
