filtering based on domains and port numbers

[GtTmy]

Tinyproxy version

1.11.0

Issue

I'd like to filter accesses based on domains and port numbers.

I wrote a filter file and a conf file below. I hoped that accesses to google via port 80 would be allowed.

google\.com:80$

User nobody
Group nobody
Port 8888
Listen 10.48.10.10
Bind 10.48.10.10
Timeout 600
DefaultErrorFile "/opt/tinyproxy-1.11.0/share/tinyproxy/default.html"
StatFile "/opt/tinyproxy-1.11.0/share/tinyproxy/stats.html"
LogLevel Connect
Upstream http proxy.example.co.jp:8080
MaxClients 100
Allow 10.48.10.20
ViaProxyName "tinyproxy"
Filter "/vagrant/tinyproxy_conf/filter"
FilterDefaultDeny Yes

But tinyproxy refused accesses via port 80.

Are there any way to specify domains and port numbers?
