Hello Yonathan and others,
The webservice that I am using is asmx.
In the meanwhile I have found a solution for this problem, ans it is quit simple…
I have added the website, where I was sending the message to, to the list of addresses where the proxy server should not be used!
I have done this in Internet Explorer:
Tools -> Internet Options -> Connections -> LAN settings -> Advanced -> Add the website to the list of Exceptions.
Use semicolons to seperate entries, and do not use spaces in the list!
I do not know if this is a option for everyone, but it works for me!
Robbish.
