Responding with binary image

I know my full rule will need to include the html. What I expect to code is:

 

 

if (URL is the image URL) {

 

respond with the image contents

 

} else {

 

respond with go-away HTML, which references the image URL

 

}

 

 

What I'm trying to avoid is having an entire HTTP server (redundant for high availability, of course) sitting around just to serve up on 1500 byte PNG image in emergencies. (I could rely on some of my existing servers, of course, but that assumes that the problem doesn't lie with any of them.)

 

 

The referenced iRule still relies on some other HTTP server to serve up the .wav file.
