We've had several people report that they are using Microsoft ISA server to
connect to their Vault server. One of the issues that we've run into with
testing proxies in house is that ISA seems to open a new connection for
every request, instead of respecting the keepalive setting. You can notice
the problem immediately if you connect to server on a 2000 pro or XP box,
since those versions of windows limit the number of IIS connections to
somewhere near 10. That means after the tenth time that the Vault client
talks to the server, the server will respond with messages about being too
busy.
The questions for people using ISA proxies. How are you getting around
this? Are you running the Vault server on 2000/2003 server? Is there a ISA
proxy configuration setting to tell it to respect keepalive? Does the proxy
opening new connections degrade your performance?
I would appreciate hearing more from people who have successfully worked
around this issue.
