Error 413 Request Entity Too Large

[Rowan @ Jetboy]

Cheers Per. Nick Tailor's been helping out off-list as well, and I've ended
up with:

 

DAEMON_OPTS="-a :80 \

             -f /etc/varnish/varnish.vcl \

             -p http_req_size=65536 \

             -p http_resp_size=65536 \

             -p sess_workspace=262144 \

             -p thread_pool_min=250 \

             -p thread_pool_max=2000 \

             -s malloc,4G \

             -S /etc/varnish/secret \

             -T localhost:6082"

 

I tried increasing http_req_size and http_resp_size first, together with
http_req_hdr_len and http_resp_hdr_len, but I was still getting reports of
problems. Bumping up sess_workspace as well *seems* to have fixed things,
but time will tell. Another fix was to get the client to clear their
cookies, but I don't know whether this is a temporary or permanent solution.
The problem seemed to be isolated to IE/Windows, but included IE8/Windows XP
and IE9/Windows 7. I can't replicate the problem use virgin Windows installs
on VMs or other Windows boxes I have access to. The user with IE8/Windows
had no problem accessing the forum on a non-Windows tablet via the same ISP.
While having a (tentative) fix is great, I still don't know why these users
were having the problem in the first place.

 

Thanks to both.

I'm not 100% sure but if memory serves me well you need to tweak this one:

 

       http_req_size

 

              . Units: bytes

 

              . Default: 32768

 

              Maximum  number  of  bytes  of  HTTP client request we will
deal

              with.  This is a limit on all bytes up to the double blank
line

              which  ends  the  HTTP  request.   The memory for the request
is

              allocated from the session workspace (param: sess_workspace)
and

              this parameter limits how much of that the request is allowed
to

              take up.
