I'm getting ready to try 2.5 HAProxy on my system and see http comression is recommended.
I am running Apache 2.4.52 and have for years tried to keep its TLS security as good as possible according to what advice I get from the Apache docs and SSL Labs. From those sources I thought https should not use compression because of some known exploit, so I'm not currently using it. My sites get an A+ rating from SSL Labs testing. So, not being at all an expert, I plan not to use the compression (although I've always wanted to). Perhaps I'm not as up-to-date as I should be (this is a hobbly, but it's an important one, although I can't spend the time on it I would like to). Your thoughts and advice are appreciated. -Tom
