QFE 810814 Expect: 100-continue

[Kumarforg]

Hi,
I am looking to skip sending "Expect:100 continue" request to a proxy while
calling a webservice from my win forms client.

I need this because the proxy apparently does not understand the header and
returns "417 expectation failed", stalling my invocations.

I found that the QFE 810814 allows for something similar.

Can anyone please confirm if i am on the right track.
I need to suppress the request form the webservice client's end.
Does this fix also work for Framework 1.1?

Answers to these would help me avoid using up one more of my PSS calls if
the QFE is not relevant to me and would be greatly appreciated.

Thanks in advance
