Is there a way to intercept page HTML source before it's served

[LP]

Hi,

After html of .aspx page has been generated, but before it has been sent to
a client, I want to interecept it, and slightly modify it. I can't find
anyway to get html of a page. How can I do that? I need that because I need
to modify behaviour of a component that someone else wrote, but I don't have
its sourcecode. Thanks

Could you inherit and override some of their methods?

Hello lp,

I think you probably want to look at the HttpResponse.Filter [1] property.
This is a Stream derived class that you can hook up to do whatever you need
with the response stream prior to it being sent to the client. Here [2] is
an example.

Enjoy!

For example: use Page.render() to get the rendered HTML source then modify
it and send it out by Response.write()... on PreRender event?

Not very sure about that.
