Existing "compression" filter is a multi-purpose filter that will try to compress both requests and responses according to "compression" settings, such as "compression direction". One of the pre-requisite work identified to implement decompression filter is that we needed a way to manually define the sequence of enabled filters to chain them in the proper order to make compression and decompression chains work as expected in regard to the intended use-case. Due to the current nature of the "compression" filter this was not possible, because the filter has a combined action as it will try to compress both requests and responses, and as we are about to implement "filter-sequence" directive, we will not be able to change the order of execution of the compression filter between requests and responses. A possible solution we identified to solve this issue is to split the existing "compression" filter into 2 distinct filters, one which is request-oriented, "comp-req", and another one which is response-oriented "comp-res". This is what we are doing in this commit. Compression logic in itself is unchanged, "comp-req" will only aim to compress the request while "comp-res" will try to compress the response. Both filters will still be invoked on request and responses hooks, but they only do their part of the job. From now on, to compress both requests and responses, both filters have to be enabled on the proxy. To preserve original behavior, the "compression" filter is still supported, what it does is that it instantiates both "comp-req" and "comp-res" filters implicitly, as the compression filter is now effectively split into 2 separate filters under the hood. When using "comp-res" and "comp-req" filters explicitly, the use of the "compression direction" setting is not relevant anymore. Indeed, the compression direction is assumed as soon as one or both filters are enabled. Thus "compression direction" is kept as a legacy option in order to configure the "compression" generic filter. Documentation was updated. |
