Tips to Handle Request/Response Size

In general, web servers implementing the HTTP 1.1 protocol do not place any prior limit to the length of characters in the URI and post requests. So practically all the modern browsers built on HTTP 1.1 should not restrict any length of data, but servers implementing this protocol restrict the data size if the URI size is more than 255 bytes.
In all practical purposes, this solution is tested in Akamai (as a CDN), Apache (as a Proxy/Reverse Proxy/Web server) and Adobe-AEM (as a CMS). But the solutions are generic in nature and can be applied to individual setups or combined as a whole.
