To improve page-rendering time a Citrix Administrator needs to overcome the connection limitation by enabling client browsers to simultaneously download more resources.
What should the administrator enable while configuring the front end optimization (FEO) feature?
To improve page-rendering time and allow client browsers to download more resources simultaneously, the administrator should enable domain sharding. Domain sharding is a technique that allows browsers to spread resource requests over multiple domains (or subdomains). This helps overcome browser connection limitations, leading to faster page loading times.
