Hi
I have problems with the following vcl-script:
if(req.http.Cache-Control == "max-age=0") {
set obj.ttl = 0s;
pass;
}
Guys, when you quote VCL code, please also tell us which
function you do this in...
sorry, this is in vcl_hit()
With this snippet in vcl-hit EVERY obj will get fetched (if there is
a Cache-Control header or not). Even when I change the code to
if(req.http.Cache-Control == "thiscanbeneverfound") {
set obj.ttl = 0s;
pass;
}
EVERY obj is fetched from the backend.
Sounds bogus, can you please enable the vcl_trace parameter
and send me a varnishlog -o output ?
I even changed it to this (the x is intentional!):
if (req.http.Cache-Controlx == "maxage=0")
{
error 200 "foo";
}
and it does not deliver anymore because the child is dying.
Cache child died pid=54760 status=0x8b
Clean child
Child cleaned
start child pid 54761
Child said (2, 54761): <<Child starts
managed to mmap 8589934592 bytes of 8589934592
Ready
CLI ready
the first req is fetched and inserted. the second request than crashes
in vcl_hit I think. But since I changed it to Cache-Controlx it should
never match.
some more output:
