Hi Ryan,
So if I'm understanding you correctly, then by adding in "
service.RequestFactory.MethodOverride = true;" to my code, I basically send
delete requests using an HTTP POST instead? And by doing a POST instead to
perform a delete action, I shouldn't run into this 302 redirect error? I
have this feeling that I'm not understanding you correctly.
When I tried to add the line "service.RequestFactory.MethodOverride = true;"
to my code right before I sent the Delete request, I got a compilation
error:
`Google.GData.Client.IGDataRequestFactory' does not contain a definition for
`MethodOverride'
I took a look at the CalendarService.RequestFactory methods, and it didn't
mention anything about a MethodOverride. Perhaps you mistook the
RequestFactory class for the GDataGAuthRequestFactory instead of the
GDataRequestFactory class?
Lastly, the article that you mentioned tells me to keep the gsessionid or S
cookie for future reference, but I guess I still don't know how to grab this
when my request fails and I get a 302 redirect error. My exception handling
isn't grabbing this information for some reason and is only telling me that
the request timed out with the following code:
try { firstMatchEntry.Delete();}
catch(GDataRequestException error)
{
Console.Write("Received an exception: {0}",error.Message);
}
Do you have any advice for me on handling this situation so that I can store
the new redirecting gsessionid?
Thanks again!
Elliott
