Dear Expert,
I'm using:
- Squid Cache: Version Squid Cache: Version 2.7.STABLE6
My question is.
When i put the following headers to (my iis 6.0 )web site
cache-control
stale-if-error=1800, stale-while-revalidate=600
squid always misses asp pages
here is the refresh pattern from squid
refresh_pattern -i www\.xxxxxxxx\.xxx\/ 180 100% 320 reload-into-ims
override-expire ignore-no-cache ignore-private override-lastmod
ignore-reload
thanks in advance
The purpose of stale-while-* is to permit your site to be provided from
cache after it goes stale while it is updated. To a maximum of 600
seconds past its expiry time.
The purpose of those ignore-* an override-* settings it to fool the
proxy into thinking objects are not-stale for far longer than they are
reliable. 320 minutes past their actual expiry time to be exact.
Figure that for logic ... 600 sec > 320 min ??
Anyway the stale-* should not be having any effect on your cache
provided objects. They are well over 600 sec defunct by the time Squid
acknowledges they are stale and starts revalidation.
2.7.STABLE6 is very old now. Please try the 2.7.STABLE9 release. This
may be a fixed bug already.
