Dear friends, i wrote a asp.net webservice using vs 2008 .net framework 3.5. this service runs over https. it gets the parameters from the client and sends this to another application and then the answer from that application back to the client. It works sometimes fine, bud sometimes im getting this exception: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Net.WebException: The server committed a protocol violation.

Seems your webservice is accessing other webservice, right? If you're using Visual Studio, you can just reference the other webservice (Right click on project -> Add Web Reference). VS will automatically create a new class encapsulating the webservice, so you just call for WebServiceClass.PS_CardsWithPersonReq method with the parameters. You might need WS Secutity to authenticate.
