  • ISA 2004 Filter

    I keep getting sites blocked by the HTTP filter in ISA 2004. The error is

    Blocked by the HTTP Security filter: URL contains ‘.’ in the path

    I have searched everywhere and there does not seem to be a way to turn this off. I gather you could do it in ISA 200 using settings in UrlScan (AllowDotInPath) but this is not used in ISA 2004
    As it even blocks some Microsoft sites I am not sure how useful it actually is!

      Beleive me, I spent almost a complete day doing searches on Google, Microsoft etc. Nothing seems to actually mention the actual message I get
      ( Blocked by the HTTP Security filter: URL contains ‘.’ in the path
      ) and how to configure/disable this one particular filter. Hence the reason for the post

          Well I believe I have found the answer! It is the option to ‘Block requests containing ambiguous extensions’ that seems to be the key. If you turn this off then it does not block the sites we had issues with before. Turning back on, problem appears. Even with this info I have not found any references to the two being linked! Would have been handy for Microsoft to refer to this setting somewhere in documentation and / or error message!
