什么是var文件php指的是什么

Question

I deployed an PHP app on OpenShift, things are kinda working but in my php.log i am constantly seeing [error] [client IP_ADR] File does not exist: /var/lib/openshift/.../app-root/runtime/repo/public/var, referer: SOME_URL SOME_URL is different most of the time, I thought it had to do something with sessions, but sessions are working (and I changed session save path). What is the var file and why are pages referring to it?

Thanks in advance.

Answer 1

That URL is most likely the HTTP Referer. When a user visits your site by clicking on a link, the page containing the link will be send along with the request in a HTTP header. This gets logged by your webserver.

But why the error?

It could be that some part of your html/css/js is trying to include some file that does not exist, or maybe some bot is just visiting your site looking for a var file that does not exist.

Try to visit a non exiting path on your site. Do you get the same kind of message then?
