.Net web application behind WebSeal reverse proxy

Question

We are currently developing a solution that will run as a .Net application through the WebSeal reverse proxy server.

I saw some comments on the net where people had various problems with this, like rewriting viewstate.

Question: Has anyone implemented this combination of technologies and got it to work?

Answer 1

Initially, I have some problems with the ASP.Net application when accessing via WebSeal. I ran the site on the development server. What worked for me was to deploy the application with debugging disabled in the configuration file.
