Hello Henrik, I'm using LDAP authentication with one-time passwords. We have 2 proxy servers that are load-balanced with the sharp proxy super script. When the first request hits a proxy the users has to authenticate, when the next request hits the other proxy server the user has to authenticate one more time. I'm searchig for a solution to bypass the second authentication. On Wed, 19 Apr 2000 21:57:03 +0200, you wrote: >By making sure the user goes to the same proxy name for the whole >session.

Thats basically correct. But the sharp super proxy script hashes the URL to make sure same URL are always routed to the same proxy server. This provides no duplicated caching. I think this is a nice benfit. So I would like to ask if there is any way to bypass the second authentication *without* doing load-balance by user (source) or load-balance DNS.
