Quick fix for the issue 4131. Included only for linux.

[dmitry-ganyushin]

FileHTTP.cpp is include in build only for linux until further fix.

Generally I think we’d rather move in the direction of making the code portable rather than excluding certain functionality from certain platforms. That’s a slippery slope with an unpleasant end.

That is only a quick fix to make build for FreeBSD (untested on FreeBSD)

[eisenhauer]

Dmitry, I'm going to close this because PR #4138 takes care of this problem by making the file in question compile on FreeBSD.

Auto tests are missing. How to test functionality?

On step at a time. PR #4138 just adds a #include so the build isn't broken on FreeBSD. I'll do windows too because that's pretty quick and easy. Adding tests and other mods will probably wait until we have a performant use case. For now, just trying to keep this code around in the anticipation that we might have such a case in the future.
