Squid users, I am replacing ICP with HTCP in a configuration with 2 and one with 4 squid servers. When testing I can see that besides the HTCP_TST neighbor cache hit test it sometimes sends a HTCP_CLR to purge content on a neighbor. What I do not know is when or why it does this and if I want this behavior? All the documents I can find and information only covers HTCP_TST. Also I have read about warnings on forwarding HTCP_CLR commands because it might create a loop. It does seem to be what I would want when using 4 servers, does anyone have any experience with this?
