Many Thanks for your answer
You mean that in production i should add additional header to my purge request because it stored this with the header content like the ip address of first varnish
OK, for purging i need wich header to add to my purge request and how can i get that what are that? And how they stored and how can i purge them

Best Regards

Try this when purging

varnish ram: curl -v -k -X PURGE http://192.168.200.13/Naserfeiz.mp4 -o /dev/null -H "newtrack: yes"

varnish file (2nd one): curl -v -k -X PURGE http://192.168.200.12:8080/Naserfeiz.mp4 -o /dev/null -H "newtrack: yes” -H "Host: 192.168.200.13<http://192.168.200.13/Naserfeiz.mp4>”

Notice the difference? You to understand HOW content is stored in varnish’s storage in order to understand how to evict it - my comment about the hash routine

Thanks

I dont understand your message,

Subject: Re: Varnish doesnt purge

I appreciate Guillaume’s diplomacy :)

Your issue (one of them at least) is that in your cascaded varnish setup the hash key of the cached url, in both varnish storages, is the one you use to originally access the asset. Your vcl hash routine might also be a custom one.. that would be the next thing to look at if what I’m saying here doesn’t fix it.

So, purge
http://192.168.200.13/Naserfeiz.mp4
and NOT
http://192.168.200.12:8080/Naserfeiz.mp4
when in the cascaded setup

Cheers

Subject: Re: Varnish doesnt purge

I do all steps now again, this is the resault:
STEP ONE:
First of all i configure a varnish (with file backend) in front of swift/Nginx and i ask the url that exist in swift with curl,

varnish-file$curl -I http://192.168.200.12:8080/Naserfeiz.mp4 -H "newtrack: yes"

HTTP/1.1 200 OK

X-Varnish: 2
Age: 0
Via: 1.1 varnish (Varnish/6.0)

varnish cach that object and then i purge the url:

varnish-file$ curl -v -k -X PURGE http://192.168.200.12:8080/Naserfeiz.mp4 -o /dev/null -H "newtrack: yes"

########

STEP TWO:
First i restart varnish file and varnishlog then:
I add another varnish (with ram backend) in fornt of the varnish file and then i ask the url again in varnish ram (because it is my frontend server and users can access media though this server):

varnish-ram$ curl -I http://192.168.200.13/Naserfeiz.mp4 -H "newtrack: yes"
HTTP/1.1 200 OK
Server: nginx

X-Varnish: 2

Accept-Ranges: bytes
Connection: keep-alive


First varnish file cached the url and then Varnish ram fetched the object from varnish file and cached it , then i purged that url in varnish ram and it purged successfuly and it exactly removed from cached:

varnish-ram:~$ curl -v -k -X PURGE http://192.168.200.13/Naserfeiz.mp4 -o /dev/null -H "newtrack: yes"

Subject: Re: Varnish doesnt purge

Yes it does, we have already proved it./

Each instance purges and will refetch the object for its respective backend. I explained how to test: start with the origin, change the data and check that you actually get the new object. Then add a varnish layer, purge, check, repeat.

You are testing everything at once and are unable to isolate the issue because you refuse to take things step by step, and spamming won't change that.

I'm sorry but until you have tested each layer individually and identified the one that fails, I won't be able to help.
