Bravo. I haven't tried the patch yet with OpenACS, but it seems to work great with ACS Classic, with one little tweak (courtesy of Johnathan Liu at Ybos). The included file request-processor-procs.tcl had some extra code in it, not germane to the patch, that didn't work with our setup. The patch code is clearly marked off in the file - in rp_filter and a couple of procs at the end - so you can extract it quite easily and add it to your existing request-processor-procs.
