Puspin stops respecting URL authority on subsequent `grip-link` requests

[eduardbareev]

the routes file:

*,proto=http,ssl=no,path_beg=/sse 172.18.0.5:80

Client calls pushpin and requests /sse, pushpin, calls 172.18.0.5 in turn.

172.18.0.5/sse responds with grip-link header set to <http://192.168.2.45/s.php>[…]

172.18.0.5/sse:

[…]
grip-hold: stream
grip-channel: channel_123
grip-channel: channel_777
grip-link: <http://192.168.2.45/s.php>; rel=next; timeout=3
[…]

Pushpin follows grip-link: and calls 192.168.2.45 requesting /s.php.

192.168.2.45 log shows the first and only request from pushpin:

"GET /s.php HTTP/1.1" 200 14 "-" "-" "-"

http://192.168.2.45/s.php response also includes grip-link header set to <http://192.168.2.45/s.php>[…] (same URL).

grip-link: <http://192.168.2.45/s.php>; rel=next; timeout=5
Grip-Hold: stream

Pushpin sends subsequent /s.php requests to 172.18.0.5 instead of 192.168.2.45, as instructed by grip-link.

172.18.0.5 log:

 "GET /sse HTTP/1.1" 200 15 "-" "curl/8.12.1"
 "GET /s.php HTTP/1.1" 404 153 "-" "-"       
 "GET /s.php HTTP/1.1" 404 153 "-" "-"       
 "GET /s.php HTTP/1.1" 404 153 "-" "-"       
 "GET /s.php HTTP/1.1" 404 153 "-" "-"
