[squid-users] cache github zip repositories

[Hardik Dangar]

*Amos,*

Thanks for the reply but it seems i am not able to tell you what i
want to do. i don't want to cache repo files. i want to cache .zip
files only. i don't want .git file to cache but only .zip files which
are fetch from github.com,

Also you have said things about commits but i am talking about zip
file which is given by github via download button or composer fetches
those files via command line directly. as soon as someone commits zip
file's ETag is changed when you fetch it.

So there is no way to achieve this ? Do you think there is a way to
achieve this ?


*Consider: how does Squid know the ETag has changed on the
server?**What you know about things happening in RL is not what Squid
knows.*
