however, i am getting the exception, unable to evaluate expression because the code is optimized and usually, you fix it by adding a false to your response.redirect.
I understand that if you put a Response.Redirect inside a try-catch that you're going to get this error unless you specify the 2nd param of the redirect as false.But even looking at this article (PRB: ThreadAbortException Occurs If You Use Response.End, Response.Redirect, or Server.Transfer) I still don't understand why I have to set this to false for this particular line of code...we've always had true for that param until I wrapped that in a try-catc

At my current place of employment, a university, we are going to take a stab at making a mobile browser-oriented section of our web site. I was wondering if anyone could direct me to some good resources that they know of for such a thing. Primarily, names of books would be nice, but any kind of resource at this point would be extremely helpful. We are approaching this as more of an HTML project at the moment, so the resources don't need to be Asp.Net based, but such things would be great too.

I am wondering are there any standard mechanisms available to protect the asp.net asp code in the client browser ? I found some references to windows script encoders. Question is,are these script encoders encodes both aspx and code behind source ? If aspx is encoded with the windows script encoders then how client browsers can decode it? Are they aware of the encoding algorithms ?Or can we control the client browsers ( IE, Firefox, Chrome etc) to disable the view source option in the Tasks Menu when web site a loaded in them?
