Proxy cache for php site

[lpugoy]

I'm sorry, but I don't understand the effect of cookies on proxy
caching. I'm trying to implement the same configuration as the one
referred to, and I'm also having trouble in that it doesn't seem to be
caching. I'm also using httperf. For every request the backend does
return a different cookie. Is this what is preventing the caching from
happening? 

In the debug log, I found some entries that refer to the cache. They are
below:

2011/11/08 20:51:45 [debug] 21434#0: *1 http cache key:
"httpwww.site.comGET/"
2011/11/08 20:51:45 [debug] 21434#0: *1 http script var: ""
2011/11/08 20:51:45 [debug] 21434#0: *1 add cleanup: 091D56A4

2011/11/08 20:51:45 [debug] 21434#0: *1 http file cache exists: -5 e:0
2011/11/08 20:51:45 [debug] 21434#0: *1 cache file:

2011/11/08 20:51:45 [debug] 21434#0: *1 add cleanup: 091D56E8
2011/11/08 20:51:45 [debug] 21434#0: *1 http upstream cache: -5

What do they mean? Thank you.
