in browser cookies creating name __utma,__utmb , on if reject cookie creation.i think cookie google analytics.anybody know how google creating cookie browser not supporting cookie creaton.thanks

yes, google analytics' cookies.

here's how ga sets/updates them:

when browser requests web page contains ga tracking code (gatc), gatc sets/updates cookies in browser. gatc sends data held in cookies ga servers via http request __utm.gif (aka, "tracking pixel"). data held in cookies appended request along other information. can identify of information taken cookies checking request " utmcc"--the cookie values on right side, e.g.:

utmcc=__utma%3d117243.1695285.22%3b%2b __utmz%3d117945243.1202416366.21.10. utmcsr%3db%7c utmccn%3d(referral)%7c utmcmd%3dreferral%7c utmcct%3d%252fissue%3b%2b

in basic implementation, google analytics creates/sets/updates three first-party cookies:

__utma: visitor id, persists 2 years;

__utmb: session id, persists 30 minutes of inactivity

__utmc : session id, persists until user quits browser;

these aren't cookies ga uses, these standard set; instance, __utmz used store values of ga-account-owner-defined campaign variables; __utmv used create custom visitor segments, , __utmx google website optimizer (split-path testing).

the visitor identifier, __utma, comprised of 4 components: domain hash, random unique id, timestamps (marking initial visit, previous session, current session), , session counter (just single integer); i.e., (domain hash).(random).(time initial).(time previous).(time current).(session count)

the session identifiers, __utmb , __utmc, comprised of domain hash + time, , domain hash, respectively; i.e., __utmb = (domain hash).4.10.(time); __utmc = (domain hash)

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
