I was testing my website with Opera and noticed that when viewing any page with the VPN enabled it would not receive gzipped files (compared to VPN off where it would). I did not check the headers that were received by the server, but I assume that the VPN is stripping the accept gzip headers from requests passed through it.
Is this a known issue and is my description accurate? Is there something I can do serverwise to enable sending gzipped files to browsers using the Opera VPN? Are there security concerns related to doing so?
This was the latest Opera browser for Windows x64
