I'm running isa 2004 and it is running well with the exception of getting access to web sites using http. Getting access to secure sites using https works but trying to access web pages using http produces this error message fro isa:
Error Code: 502 Proxy Error. The request was rejected by the HTTP filter. Contact your ISA Server administrator. (12217)
I have a policy setup in isa that limits web access to http, https and ftp.
I've configured the proxy settings in netscape to use my isa server.
There are no issues when I use IE but I don't know why I can't access web pages using http via netscape.
