I can't really tell what you're having problems with... If you're having problems viewing a specific website it's most likely not going to be a problem with your computer. Check the cache of the site on google or bing to confirm it.

Oh, and sentences.

nginx handles web-based protocols server-side, much like Apache.

tl;dr It's the website's problem, not yours.
