Hi Naga,
The Enhanced Experience Composer will make calls with paths that will match the page you are loading in the EEC. For example if you are loading this page in the EEC:
https://DOMAIN/folder1/folder2/file.html
The the referrer from the EEC will show up in your logs like so:
https://**-proxy.adobemc.com/folder1/folder2/file.html
The ** portion will vary by region.
For protocol and port it will match the protocol that you use in the url you enter. So in the case you've described it will be https and the related port of 443.
Here is a sample of what the server logs will look like when the EEC has made a request to your server:
54.199.241.57 - - [17/Jun/2016:09:55:30 -0600] "GET /js/library/select.js HTTP/1.1" 304 124 "https://apac-proxy.adobemc.com/games?vz_t=b&mboxEdit=1&mboxDisable=1&vz_url=https%3A%2F%2Fwww.gamesd..." "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0"
