I've made some further updates both to the code and documentation since posting. One change is to support inserting a harness anywhere in the filter chain. This addresses the point Graham raised about having two separate mechanisms: it means the old mechanism can be entirely replaced (provided of course I provide easy-reading "howto upgrade" documentation).
I would find this easier if it were under CVS, and I'd like to put it under httpd CURRENT, at modules/experimental/mod_filter.c (plus the corresponding documentation pages, of course). That should help with integration ahead of 2.2, including test-driving with existing filter modules, and will make it easier to coordinate the API updates in util_filter. Is this something that wants a vote? Anyone else have strong feelings for or against putting mod_filter under CVS? -- Nick Kew
