"The URL contains an invalid parameter" error after upgrade UAG to SP2 RRS feed

  • General discussion

  • Hello,

    We notice that in some occasions, after upgrading UAG to SP2, initial access to the portal fail with the following error:

    "You have attempted to access a restricted URL

    The URL contains an invalid parameter"

    Invalid parameter

    This seems to happen because SP2 (and maybe earlier security hotfix) add a special parameter URLHASH and the InternalSite_Rule1 not get updated to include it.

    To fix the issue you need to add the following parameter to InternalSite_Rule1 rule:

    Name: urlhash

    Value: [0-9a-z\-]+

    Length: 0:50


    Hope this helps,
