Re: [squid-users] persistent http with pushback

Sorry, I am not sure I understand what you are doing here or exacly
when you are getting problems. Are you saying that you cannot succeed
in getthing these replies at all back via Squid, or that it does not
work to keep the connection persistent for a second request?

What I can tell is that the reply headers you have shown can't keep a
HTTP/1.0+ persistent connection, and will be closed when the reply is
finished. HTTP/1.0+ persistent connections require a Content-length
reply header. (HTTP/1.1 has a mode where you can keep connections
persistent without the need of Content-length, but Squid is not yet
HTTP/1.1 and neither is your reply)
