Hello everyone.
I’m just wondering if someone test this website on his Hotspot sever while you didn’t authenticate to the hotspot server so then you are not able to open any website.
http://www.varzesh3.com/
I don’t have any walled garden for this website. But i’m wondering why only this website is opened before authentication.
I don’t have such problem with other website. Just aware of this 
also checked my firewall. nothing special …
Thanks in advance

Nope.
I can’t access it while logged out.
There’s a possibility that you have a malware on your PC, and when accessing this website, it’s pulled from cache, rather than from the internet. Check your hosts file, and try from a different PC.
Oh, and before any mod removes your post with an accusation that you’re spamming, I suggest you surround that link with “code” tags, to prevent a link being created.
Thanks for reply and OK for 2nd part 
and you know first time I noticed that I was trying that website via one of my customer’s Apple iphone. so there is no any windows virus.
and I don’t think there is problem with computers and viruses… They are fully protected.
Maybe you’ve configured a web proxy, and it’s in there? And the logged out users could be noticing it if there are IP bindings (of type “bypassed”) for their devices.
The IP of this site seems to be 94.182.163.3. Check if you have any special treatment for this IP or it’s subnet (which appears to be 94.182.0.0/16) anywhere on the router. To more quickly find it, do an “export” of the entire router, and search through the file.
If you use any routing protocols (BGP, RIP, OSPF), see if they have anything to do with this IP or subnet (e.g. if they’re dynamically creating a route).
It seems this website is caching it self to my computer (or smart phones) in order to open up faster in later. even the pages I didn’t open (1 saw one or 2 page of it).
Hop fully after minutes and minutes these unwanted caches will erase and I can get rid of them.
Thank you boen_robot for caching idea. Maybe in future (again) I will set my browser cleaner software again for my clients…
