Cache MISS and HIT

[andre wang <andre.ease@xxxxxxxxx>]

hi all:

    I have an issue.
    My squid is running on my localhost at port 3128,  when i make
http request with squidclient:
    squidclient -m HEAD http://example.com/  it returns :
    X-Cache: MISS from localhost
    X-Cache-Lookup: MISS from localhost:3128 (it's normal as the cache
is empty now)

   Trying send the same http request many times, squid returns MISS.
Then I make the same HTTP request using GET method instead of HEAD.
After done GET request, i come back sending squid HEAD request:
squidclient -m HEAD http://example.com/, Squid alway return HIT.

   I'm confused, is that normal, can anyone help?

thanks
