These are all basically private inside ESP8266WebServer, so I don't see any issue w/user classes even though they are virtual methods.

Actually, @devyte, while what you say is possible, IMO they're virtual because we need to store a pointer to a generic RequestHandler in the webserver (i.e. internal considerations, not custom overloads). Overloaded classes would suffer object slicing if we stored a pointer to the base class in the WebServer object, so these functions need to be virtual (even though I was able to rewrite the WebServer class to be a template w/o virtuals). |
Passing String by value means a full copy-constructor/temporary string creation which is slightly inefficient. Avoid that by using const references.
