Why doesn't it cache? (CERN httpd)

Post by Claus Assma » Sat, 05 Aug 1995 04:00:00

Hello !

We have a problem with a proxy caching CERN server.  It doesn't cache
as much things as we would like.  Here are two examples:

It cached:

HTTP/1.0 200 Document follows
MIME-Version: 1.0
Server: CERN/3.0
Date: Friday, 04-Aug-95 09:20:13 GMT
Content-Type: text/html
Content-Length: 1748
Last-Modified: Friday, 16-Jun-95 20:04:00 GMT

But it did not:

HTTP/1.0 200 OK
Server: HTTPS/0.96
MIME-version: 1.0
Content-type: text/html
Date: Saturday, 1-Jul-95 13:38:11 GMT
Last-modified: Saturday, 1-Jul-95 13:52:12 GMT
Content-length: 21334

Both contain at least a 'Last-modified' header, and the config files

CacheLastModifiedFactor                 0.2

so it should keep the second file too, right?  The Date: of the second
is strange, could this be the problem ?

Can anyone tell me, why httpd might not cache it (where should we look,
can we tell the server to give me the reasons why it didn't cache the
document) ?

We have 800MB reserved for caching, but only about 90MB is used.  Most
of the time the stuff is reloaded from the net, which is especially
frustrating since the connections are very slow for some weeks now.

Many thanks in advance,

Claus Assmann

is someone out there, who used cern-httpd as proxy-cache under Linux?
If so, could you please send your httpd.conf-file for example.
