[users@httpd] garbage collection mechanism with mod proxy

Title: garbage collection mechanism with mod proxy

Hi,

I am working with apache 1.3.27 with mod proxy.

I checked the garbage collection mechanism with the following configuration:

    CacheRoot "/var/cti/db/apache"

    CacheSize 10

    CacheGcInterval 0.2  

    CacheMaxExpire 1   

    CacheLastModifiedFactor 0.1 

    CacheDefaultExpire 1

I did the following tests:

On time 0 :  sent a request to file 1 (4kb) -   the file was stored in the cache

On time 8 :  sent a request to file 2 (4kb) -   the file was stored in the cache

On time 9 :  sent a request to file 3 (4kb) -   the file was stored in the cache

On time 13 : sent a request to file 4 (4kb) -   the entire files were removed from cache, and file 4 was not stored

On time 14 : sent a request to file 4 (4kb) -   the file was stored in the cache (the process repeated itself)

This process seems wrong to me, because according to the documentation the GC should work as following :

new request arrives
apache determines if garbage collection needs to occur ( "garbage_now < lastcheck + every", where garbage_now is the current time, lastcheck is the time of the last garbage collection, and every is the gcinterval)
if garbage collection needs to happen:
apache sorts files according to expiration date
if file is expired, then it is removed from the cache
if cache is still too big, remove oldest files until we get down to the configured CacheSize




Can someone explain to me what's wrong?
