ATS forwards extra carriage returns in header line endings

[kenballus]

Hi,

If you send ATS a request with extra carriage returns in header line endings, it forwards them as-is.

For example, if you send the following request:

GET / HTTP/1.1\r\n
Host: echo\r\n
Extra-CRs: \r\r\r\r\n
\r\n

Then, ATS forwards the following:

GET / HTTP/1.1\r\n
Host: echo\r\n
Extra-CRs: \r\r\r\r\n
Client-ip: 172.18.0.1\r\n
X-Forwarded-For: 172.18.0.1\r\n
Via: http/1.1 traffic_server[a24326f7-ff3b-4679-9801-53028b257033] (ApacheTrafficServer/10.2.0)\r\n
\r\n

Note that the extra carriage returns are still present :)

If you send more than 3 extra (4 total) carriage returns in a single header line ending, though, they all get normalized away. Kinda fun.
