Hi, I am trying to get my head round what I can do with filters. I see that I have to give FilterProvider an argument that is ''provider-name'' and that ''provider-name must have been registered by loading a module that registers the name with ap_register_output_filter()''. I am looking for a list of such provider-names, but most of the documentation seems to use as examples SUBSTITUTE DEFLATE INCLUDES & jpeg/gif pack/unpack. However if I grep the source I see all sorts of others: CACHE, H2_SLAVE_OUT, BROTLI_COMPRESS, DUMPIO_OUT & many more. I do realise that it depends on what I want to do. The filters page http://httpd.apache.org/docs/2.4/filter.html gives some modules and directives ... but it is all very terse and doesn't really help in trying to understand the big picture. Are there any better references/documentation that I can look at.
