Requirement is to fetch reports for connection made to proxy port.
Port 8080 for example.
By default access logs does not note Proxy-Port information however we can configure a costume log format.
First you will need add 's-port ' to access log format, Once the new format is save proxy will start recording proxy port information in access logs.
Note this will not applied any old access logs , only new access logs will have information.
Next Proxy would forward these logs to configured reporter.
In reporter you need to configure custom log field for ' s-port '
Once you reload the database , Reporter would start recording new custom log field in this database.
You can add custom log field in full detail log report.
After sometime , once access logs with new format are reporter you can also create custom reports for proxy port.
