Hey Edward,

First congrats!.
I hope we can help you to figure out the relevant details.

I am not sure why you have spoken to AWS teams about Squid-Cache, may I ask what OS are you using in AWS?
Also what version of Squid are you using?
The timeout settings are "critical" indeed but depends on what you are using and doing with Squid-Cache.
Despite to the fact that https://www.visolve.com/squid/squid30/timeout Is in a way still a lead it's not "up-to-date"

Please note that without understanding what issues have you been facing and the purpose of the Squid-Cache instance(s?) there is no way to even guess what might fit your needs.

Subject: [squid-users] Connection Timeouts

We had a person leave and I got selected to update and maintain our squid proxy.   We are talking to AWS and they told us that we needed to change the connection_timeout value from the default to 5 min.

We have people stress testing out installation and I was concerned that if connection timeouts are too long we may see congestion. 

Should I be worried that connection timeouts will use up file descriptors at a higher rate?

And what might be the options?

Doing and internet search I found a web page at https://www.visolve.com/squid/squid30/timeout.php and in the TIMEOUT description I read

Timeout parameters in Squid can be based on overall connection timeouts, peer-specific timeouts, site/domain-specific timeouts, request-specific timeouts etc. Proper setting of timeout values is critical to optimal Squid performance. Relevant parameters for timeout settings are listed”

Is it possible to narrow the connection timeout to a specific site?  I looked at the website information, squid documentation and did an internet search.

I did not see anything that narrowed the timeout to a specific timeout. 

I am trying to set connection timeouts to AWS sites, but keep connection timeouts to the default, because it is working well.
