Re: Help soap call hangs

Leif,

I cannot say I've experienced this, but something to notice is that 
the 2.2 code did not have any timeout for establishing the 
connection, just for the request/response.  I would think that what 
you are seeing (no timeout) is possible if the SSL connection is 
established at the TCP level, but the SSL handshaking does not 
proceed to conclusion for some reason.  I am not sure how to verify 
this without either sniffing the line (even then, I'm not sure how 
you would read some of the  encrypted SSL handshaking) or turning on 
SSL debugging.
