Question

In my MVC3 application I want to remove all HTML5 tags for the output when the user is using IE < 9 to avoid using a frontend workaround.

I’ve looked in to using a HttpModule, ActionFilter, the OnResultExecuted method on a controller and inside Application_Start.

I’ve figured so far that I need to get the output as a string from HttpApplication.Context.Response.OutputStream using something like:

HttpApplication application = (HttpApplication)source;
HttpResponse response = application.Context.Response;
StreamReader sr = new StreamReader(stream);
string content = sr.ReadToEnd();

But all I get is the same error Stream was not readable.
I can write to the response with context.Response.Write.

From reading around on SO and google, MVC doesn’t seem to have the same “page life cycle” has webforms(where I’m just overring Render and it works fine) which makes sens.

So my question is how do I get the HTML as a String in MVC? Have anyone tried to manipulate the html output?

I think you should be able to use an ActionFilter to do this. I’ve seen an example of someone modifying the output stream in this blog post. or in this post.
