Monks

I'm not entirely clear if this is an apache problem or a perl problem so I'll moot it here in the hope that it is relevant. I have written a CGI script that dynamically generates a graph using the excellent AT&T GraphViz package. However, you are supposed to be able to naviagte through the graph by clicking on various vertices, and GraphViz provides a server side image map for doing this. To use my script you just specify the node of the graph to centre on as a parameter ('ec'), thus:

http://localhost/~arun/cgi-bin/egv.pl?ec=1.1.1.1

This works fine if I enter it manually as a URL and draws graphs. The URL format used by the image map is the same and thus should draw a graph by generating a URL in the form above appropriate to the node that was clicked. However, when clicked after a substantial pause a webpage saying the following appears:

Found
The document has moved here.

The 'here' part of the above sentence is hyperlinked and clicking it takes me to the correct page that I should have reached originally. So my question is, why do I not go directly to the page I want, why is this intermediate page displayed with the link to the page I want embedded in it.

Does anyone know how I can fix this?

Incase it helps, these headers are displayed above the 'Found' bit:
