@relevantprogrammer Without looking a the code, all I can say is that each of these three URLs returns what appears to be the exact same page. Are you certain you aren’t seeing a local caching issue, either at your browser or ISP? Have you tried visiting in a new private / incognito window? Have you tried loading each of the three URLs in GTMetrix to compare them?
@gregraven Thanks, you are right, it was browser cache issue.
