Hi,

I’m struggling with consecutive early-hint statements defined with if condition.

Considering below configuration:

http-request early-hint Link ">; rel="preload"; as="style"" if { path -i -m
beg /test1 }
http-request early-hint Link ">; rel="preload"; as="style"" if { path -i -m
beg /test2 }

I’m not getting HTTP 103 response to 2nd statement.
Response I’m getting with above config:

example.com/test1  response: HTTP/2 103 + HTTP/2 200
example.com/test2  response: HTTP/2 200

However if I add some dummy statement in between those early-hints like this:

http-request early-hint Link ">; rel="preload"; as="style"" if { path -i -m
beg /test1 }
http-request set-header X-Test "test-request"
http-request early-hint Link ">; rel="preload"; as="style"" if { path -i -m
beg /test2 }

I’m receiving HTTP 103 response to both statements as expected.
Response I’m getting with above config:

example.com/test1  response: HTTP/2 103 + HTTP/2 200
example.com/test2  response: HTTP/2 103 + HTTP/2 200

It looks like an issue with parsing early-hint statements which are defined with
"if” statement.

It’s my first message sent to this mailing list - so please excuse me if I miss
any information required to properly identify the problem. If I’m missing
anything - please do let me know.
I would appreciate any help here.

I’m using HAProxy version 2.4.15-7782e23



Thanks ! Indeed, I can confirm the issue. I'll try to fix it soon.



Hi,

It should be fixed now in 2.7-DEV but not backported yet. The commit:

Issue - consecutive early-hint defined with "if" condition

[Krzysztof Kozłowski]

Hi,

I’m struggling with consecutive early-hint statements defined with if 
condition. 

Considering below configuration:

http-request early-hint Link "; rel="preload"; 
as="style"" if { path -i -m beg /test1 }
http-request early-hint Link "; rel="preload"; 
as="style"" if { path -i -m beg /test2 }

I’m not getting HTTP 103 response to 2nd statement.
Response I’m getting with above config:

example.com/test1 response: HTTP/2 103 + HTTP/2 200
example.com/test2 response: HTTP/2 200

However if I add some dummy statement in between those early-hints like this:

http-request early-hint Link "; rel="preload"; 
as="style"" if { path -i -m beg /test1 }
http-request set-header X-Test "test-request"
http-request early-hint Link "; rel="preload"; 
as="style"" if { path -i -m beg /test2 }

I’m receiving HTTP 103 response to both statements as expected.
