Hello everbody. I'm using Squid3 (squid/3.1.14) on Ubuntu 11.10. I'm using it with my own-made ICAP server which is RFC 3507 compliant. The problem is: When chunked transfer encoding occurs (encapsulated http message has a body), sometimes it fails with my send function giving errno 11 (Resource temporarily unavailable). This happens when I try to upload relatively big files (around 500 KB), when I tried smaller ones, there wasn't any problem. It seems like, increasing chunk size of my ICAP server's responses temporarily solved the problem. But I need to know its reason. Is there any chunk limit or something in Squid or why this problem can occur ?
