[pve-devel] [PATCH manager v2 2/3] pveproxy: add configurable COMPRESSION

[Stoiko Ivanov]

disabling http compression is considered good practice and certain TLS-testing
scripts/sites lower the security rating if it's enabled.

compression is still on by default for the potential speed/performance gain.
