I face a problem regarding sharepoint development. I have to write a sharepoint web part. To configure that web part I call an asmx web service via soap.
The asmx shall share sessions with a pretty huge aspx site. In sesson_start of the application the browser type has to be determined by using HTTP_USER_AGENT from server variables of the request. That works fine outside of sharepoint where the aspx is certainly also used. But within Sharepoint the asmx will be the first caller. When calling with the soap client the HTTP_USER_AGENT server variable is not send by the request.
This is certainly no issue for the asmx but later on in the same session for the aspx that will be called after configuration has taken place in Sharepoint web part.
Does anyone has an idea how to force sending that information or may be what I can do differently to avoid that issue?
Any help is highly appreciated,
