Response.Flush - OnFlush event in classic ASP?

Question

Hi,

I need to rewrite the domain names on web pages served by a DLL that I have no way to change. I thought if there were events like OnFlush before Response.Flush occurs on the page I could do it all before the page is displayed. Is there a way to do this in ASP?

Thanks for your help.

P.S.: Something like Script_OnFlush in this APACHE extension: http://www.apache-asp.org/events.html

Following Nick's suggestion I have created a class that inherits from the Stream class. Response.Filter is using this class to work on the HTML content...

By overriding the Write method I managed to rewrite the domain names on the site.

    public override void Write(byte[] buffer, int offset, int count) 
    {
     byte [ ] data = new byte [ count ];
    Buffer.BlockCopy ( buffer, offset, data, 0, count );

    string myHTML = ASCIIEncoding.ASCII.GetString(data);
    string convertedHTML = myHTML.Replace("http://www.previousdomain.com", "http://www.currentdomain.com");

    data = ASCIIEncoding.ASCII.GetBytes(convertedHTML);

     _sink.Write ( data, 0, count );

    }

Thanks Nick!

Yes you can overload the Response.Filter property, which acts as a filter for all content that is returned to the browser. You should do this in the PostReleaseRequestState in the Global.asax.
