[squid-users] Transferring from one squid to another squid proxy

Hi

I,m running Master squid 2.4 (10.10.10.1)on one redhat 7.3 server and
another slave squid 2.4(10.10.10.2) server.
All request coming to 10.10.10.2 needs to be transferred to 10.10.10.1.
cache_peer is added in slave proxy

cache_peer 10.10.10.1 parent 80 3130 proxy-only

Browsing is happening fine .But all mail sites ( mail.yahoo.com,
hotmail.rediffmail.com) which has authentication is not going thru.Gives
page cannot be displayed.Any other parameters needs to added , suggestions
please.
