I'm guessing the svg encoder just writes directly to stdout. If my theory is correct, non-trivial code changes would be necessary to make this work.<br>
>><br>>><br>><br>> Thanks Frank, that actually makes perfect sense. I'm not all that familiar, but it seems that I read somewhere that a legacy version of mapserver had native SVG support, which in turn would work with fastcgi? Seems I also read native support is on the wish list for a future release as well. <br>
