Unfortunately, a client of mine still has an application based on ASP.NET 1.1.
Yes yes, I know - horribly insecure, support ending, and on and on... I've already been through that with them.
Unfortunately, their upgrade timeline is not soon enough.
In the meantime, they're trying to plug some of the larger holes... E.g. very common cross-site scripting flaws. Of course, I recommended using MS' AntiXSS Library for that (especially since many of the flaws would not be plugged with simple HtmlEncode)...
Unfortunately, AntiXSS doesn't work with ASP.NET 1.1 - or, at least as far as I know. The versions I found go back to ASP.NET 2.0 (version 1.5).
So, the question - was there a version for 1.1? If so, where can I find it? If not, do you have anything else to do the job - in ASP.NET 1.1?
