2008] I've been seeing more of these lately. Enough so that I figured I'd take some time to figure out what the problem is. It turns out that if you're going through an ISA firewall, that you'll see this error when the Web server includes a response that includes an HTTP header with a space or tab at the beginning of the header (this is a Web server problem, not a problem with your ISA firewall). However, you can change the way the firewall works so that it's more forgiving of this error. https://social.technet.microsoft.com/Forums/en-US/67962752-ee7b-4763-b284-bb9cc0bd7a2d/tmg-error-code-502-proxy-error-the-http-message-includes-an-unsupported-header-or-an-unsupported?forum=Forefrontedgegeneral Check out the solution over at: http://support.microsoft.com/default.aspx?scid=kb;EN-US;935693 HTH, Tom Thomas W Shinder, M.D., MCSESr. Consultant / Technical Writer Prowess Consulting www.prowessconsulting.com PROWESS CONSULTING | Microsoft Forefront Security SpecialistEmail: tshinder@isaserver.org MVP — Forefront Edge Security (ISA/TMG/IAG) See Also Review and Comments Name * Email address * URL * Comment * If you enter anything in this field your comment will be treated as spam * * Required field http://www.isaserver.org/blogs/shinder/isa-central/502-proxy-error-http-message-includes-an-unsupported-header-768.html The Author — Debra Shinder DEBRA LITTLEJOHN SHINDER, MCSE, MVP (Security) is a technology consultant, trainer and writer who has authored a number of books on computer operating systems, networking, and security.
