No more than 10 parallell WebService connections?

I wonder why it is that no more than 10 clients can access a webservice at a
time, and how to increase that number.

The eleventh client get a Http 403.9 (Access forbidden : To many users are
connected) error message.

Simply explanied; if I create the simple HelloWorld WebService, open 11
Internet Explorer's and give them the HelloWorld URL the eleventh IE get the
Http403.9 message. Not until I close one of the connected IE's will the
eleventh gain entry (which is really not eleventh no more, it's the tenth).

Does it matter what kind of operating system I use?

Absolutely. If you're running on XP or 2000 Workstation, I'm pretty sure this is the limit. This should be a non-issue on a 200[0|3] server box. You shouldn't really try to performance test on a workstation OS, they're just not tuned for this kind of stuff.

You are probably right, but I did find a setting in IIS where I could tell it
not to keep connections att all. The help indicated that a specified nr of
connection can be set in another version of IIS (prob 6.0 or server version).

Hi Johan,

Turning off keep-alives will sure help you go a little bit further. But
eventually you'll hit the wall on the desktop OS. The limit is desktop OS
related - the desk top license limits you to 10 simulteneous open network
connections.

I hope this helps
