Speed of checking cookie's name

checking if such a cookie exist

[Ian2k8]

If I want to check if guest has a cookie named "mysettings" using the following method.

if(document.cookie.match("mysettings"))

Is this method efficient when the website has more than 100 pages and guest has to do this checking on every page?

I once wonder if the checking speed will be seriously slow down when guest's computer has stored a lot of cookies, but because this method checks the cookie that was set at the same domain, so it is the fastest method. Right?

Here is the old chunk of JavaScript I used to use to find a specific cookie however I highly recommend using serverside language to do this instead.

var $theme = getCookie("theme"); function getCookie(Name) { var search = Name + "="; var CookieString = document.cookie; var result = null;
if (CookieString.length > 0) { offset = CookieString.indexOf(search); if (offset != -1) { offset += search.length; end = CookieString.indexOf(";", offset)
if (end == -1) {end = CookieString.length}; result = unescape(CookieString.substring(offset, end))}}return result;}

Thank you, John.

Why do you highly recommend using server-side language?

Webkit (Safari, Omniweb, and now iCab 4+) does not play nice with cookies (via JavaScript).
