The problem is not refreshing content from the CMS. Our deployment
will be Squid reverse proxying an app server that in turn talks to the
CMS for the content and adds the look and feel to the content. So
squid will be caching the final url. the challenge is to figure out
how to get squid to be
Have you tested to see if any of these concerns are in fact something
that can happen.
It is my understanding that Squid will ask the app server if the content
is new or not and if the app server says that the text is new and the
photo is old, then squid will ask for a new copy of the test
I would rather not do a restart of anything unless absolutely required
Here are the challenges we face
1) We are trying to deploy Suqid as a reverse-proxy in front of a CMS
2) We want to trying find a balance between keeping the content fresh
without affecting performance by frequently expiring
Are you sure that you need to do this?
Squid should be able to tell the difference between static and dynamic
content.
We have a dynamic JSR-168/268 portal based on Tomcat and Jetspeed
sitting behind Apache and Squid and we have never had to intervene with
Squid for 3 years.
We also have
It is all dynamic content going forward
scenarios where a cache flush would be required
1) an article is updated
2) category is updated with a list of articles.
we syndicate content to abut 150 partner and will have same
article/category with a different URL doesn't squid cache based on the
If you google squid dynamic content you will find that by default
squid does not cache dynamic content.
If it did, it would be useless as a proxy server since that would make
almost all dynamic sites unusable.
There are lots of instructions about how to trick squid into caching
content that
If you are thinking that is is dynamic content with query strings then
it's not the case. the urls will look like a directory structured
static content but the back-end app server will translate the url and
fetch the appropriate content from the CMS (alfresco)

I am looking to deploy Squid as a reverse proxy and i had couple of
questions. We currrently use Bluecoat and Sun Web proxy and i am able
to do the following things
1) How would i flush objects from cache?
2) Can i flush the entire cache without restarting Squid?
3) Can i set the configuration to
1- I think the fastest way to flush all the cache is to stop squid
then making mkfs.extX on your cache partition. I suppose you have a
separate partition for cache.
2- Is it possible ? I dunno
3- check refresh_pattern settings also you can set the minimum expiry time.
