  Additional / Second Intercept for ISAPI Reply Contact Hi, I work with a .net application that embeds calls to another ISAPI service to return images.  The images never exist but are streamed with a request like... .../GetImage.IMG?Size=10,10&Format=PNG&etc That is from a third party and all works 100%.  Great. What I would like to do is introduce an additional process (I originally thought IHttpHandler) to catch the images just before they are returned to place my own overlay (copyright) on them.  Any suggestions greatly appreciated.  Thanks in advance, Cris

  Re: Additional / Second Intercept for ISAPI Reply Contact Thanks for the reply - your hint has led me to a great wrapper for the filter events called Filter.Net. I have the usual problems of re-writing the data as the images I want to update come in lots of raw data packets... but I have posted onto the filternet site to try and get a reply - my C isn't really up to low level manipulation.  Thanks again, C
