We have installed Forefront TMG 2012 server in our network. But some times, it blocks certain URLs.
There is one gov site http://www.eproc.bihar.gov.in/ which get redirected to https://www.eproc.bihar.gov.in/ROOTAPP/BELTRON.jsp?company=BELTRON. This site is not browsing through TMG server. Without TMG Server or through ISA 2004 server, sites opens properly. But with TMG server, "Session Lost. Please Login" web page appears.
We really do not understand what is problem with TMG server? why is it not browsing web page?
Kindly help to resolve this.
Thanks in advance.
Best regards,
