HTTP server returning multiple early hints shows too many responses in "Follow HTTP Stream"
Summary
http server returning multiple early hints shows too many responses in "Follow http". When the server returns only one early hint, the view seems fine. Returning multiple early hints is allowed by the spec: https://datatracker.ietf.org/doc/html/rfc8297#section-2
A server MAY emit multiple 103 (Early Hints) responses
Steps to reproduce
- Capture Localhost
- Run this "http"-server:
#!/usr/bin/env python3
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("127.0.0.1", 9000))
s.listen()
while True:
c, addr = s.accept()
body = """\
<!DOCTYPE html>
<html>
<body>
Hello World
</body>
</html>
"""
resp = f"""\
HTTP/1.1 103 Early Hint\r\n\
Link: </hint-a.png>; rel=preload; as=image\r\n\
\r\n\
HTTP/1.1 103 Early Hint\r\n\
Link: </hint-b.png>; rel=preload; as=image\r\n\
\r\n\
HTTP/1.1 200 OK\r\n\
Content-Type: text/html;charset=utf-8\r\n\
Cache-Control: no-cache\r\n\
Content-Length: {len(body)}\r\n\
\r\n\
{body}
"""
c.send(resp.encode())
c.close()- run
curl 127.0.0.1:9000 - click on follow > TCP Stream (of one packet) and see two early hint responses
- click on follow > HTTP Steam (of one packet)
What is the current bug behavior?
In the HTTP stream view more than 103 Early Hints responses are displayed
What is the expected correct behavior?
The correct amount of early hints.
