RE: [squid-users] Accelerator not Caching for specified times.

Here is the Refresh Pattern
# www.someUrl.org 1 month
refresh_pattern -i www\.someUrl3\.org 43200 20% 1440
ignore-reload
refresh_pattern -i someUrl3\.org 43200 20% 1440
ignore-reload

I have the logfile I have grepped out the www.someurl.com so only that
record is returned.
The access log is about a meg so I put it up on the web.

Thanks for your help.

Please enable log_mime_hdrs and then show the request history of the
URL in question, and your refresh_pattern settings.

log_mime_hdrs allows us to see what is going on, but to gain an
understanding some history of the object is needed

  1) A initial TCP_MISS/TCP_REFRESH_MISS where the object got cached
  2) Maybe some TCP_HIT [remove duplicates if there is many]
  2) The next TCP_MISS/TCP_REFRESH_MISS where you think the object
should have been a HIT..

This can then be applied to rules about cachable request and your
refresh_patterns to verify if the object should really have been a
hit, or if there is a valid reason to why it was processed as a cache
miss.

Henrik
