Hi!
I'm not sure, that this is squid's problem, but this is at least squid's
related ;) Can anybody help me? Thanks in advance :)
The problems are:
I have web server, based on Apache-1.2.6 with enabled CacheNegotiatedDocs
and Squid-1.1.20 with enabled reload_into_ims. As I understand, when squid
get request on reload document, it change "Pragma: no-cache" to
'If-modified-since' and send this request to destination web server. Ok,
I'm calling my local web via proxy - and see in access_log TCP_IMS_HIT, but
don't see any activity in the Apache's access log. So, Squid doesn't pass
request to web at all. This is strange, as for me.
Second: I'm using <meta http-equiv="Last-Modified" ...> and
<meta http-equiv="Expires" ...> directives in static HTML documents. Why
resulting document in Squid's cache doesn't contain Expires: header at all,
and Last-Modified set to last access time of document, but not to used
in <meta ...> directive? I'm afraid, that Apache ignores this directives in
documents and send default parameters in his reply. Why? I think, this
second problem is cause of first.
What I need to do for avoid this problems? Probably, some additional setup
for Apache? I can't find any related topics in the Apache documentation
and in the Apache FAQ.
Here is examples of original and resulting documents:
