Support for 'expect' header

[systemmonkey42]

Hi,

I don't know if this is actively developed, but I struck an issue with a WEBDAV server where it sent an expect: 100-continue header which caused authelia to emit HTTP/1.1 100 Continue before sending the authentication results.

The auth-request.lua script immediately disconnected as soon as it saw the HTTP/1.1 100 Continue with the message

haproxy[231]: Invalid status code in auth-request backend 'be_authelia': 100

Adding the line

headers["expect"] = nil

fixes the problem.

Thanks

Not actively developed, because I consider this to be feature complete, I'll however try to respond to issues and to fix bugs (if any).

fixes the problem.

That sounds reasonable, would you consider creating a PR that fixes the issue for you? If possible include a VTest test that verifies the behavior. Explanation is here: #54 (comment)
