Hey Sam,

It seems that the goal is to fetch and save everything to disk and from disk, 
right?

 

During the time that your clients and proxy are fetching the object using 
squid, you cannot serve this "in-transit" content to other clients.

Collapsed Forwarding feature of squid should satisfy your use case but depends 
on the size of the object it might not be the right choice for you.

What objects size are we talking about?

Subject: [squid-users] different results every time

 

Hi, 

I'm querying lots of files through 4 cache servers connected through parent 
hierarchy. I clean all the caches before I start and then I query the files 
again in the same exact order. Weirdly, every time I check the logs, I see a 
different cache served a file compared with the previous test. The query 
process is done through a python script that uses wget through a proxy to the 
cache, hence the query process is really fast. 

Interestingly, if I put a delay of 1 second between each query, the result will 
be stable and same every time I run the script. 

Following a snippet from the config file after changing it too many times to 
make it re-produce the same results yet, that didn't help: 
cache_dir ufs /var/spool/squid 9 16 256
cache_mem 0 MB
memory_pools off
cache_swap_low 100
cache_swap_high 100
maximum_object_size_in_memory 0 KB
cache_replacement_policy lru
range_offset_limit 0
quick_abort_min 0 KB
quick_abort_max 0 KB

 

Can someone shed some light on the issue and how to fix it please?

Thanks, 

Sam
