| Hi Alex, I’ve uploaded a tcpdump sample of where I’m requesting an image through squid + icap and where you can see the image response being posted fully to the ICAP service. Headers passed on are Preview: 0 for RESPMOD and Transfer-Preview: *. (I only need the headers for the response) Many thanks for co-debugging. :-) Enjoy your weekend!

It is the preview. The timing of an ICAP request does not determine whether that request has a Preview stage and whether the "unexpected" body bytes were sent during that Preview stage. I am asking these questions because I want to determine whether Squid increases Preview size beyond what your server has requested or does not send Preview at all. Please share the ICAP headers of the problematic REQMOD request and the last chunk metadata of that request body. You can get the latter from a packet capture if your ICAP server does not report it in a convenient form. In fact, sharing (a pointer to) the packet capture of the whole problematic ICAP request is probably a good idea! Alex. On 5 Mar 2021, at 17:21, Alex Rousskov wrote: |
