AJAX HTTP protocol response problem with custom server -

-

i've started add http support custom c# non-webserver application seems work fine firefox/ie/chrome when typing in url directly browser - can see returned text string in page application.

the problem when try same httprequest in javascript on web page don't response chrome or firefox (it's fine in ie) - rather status of 0 httprequest object. can see application debug output received request browser , provided response browser must not response send in case exception of ie being less picky.

i've swapped between trying different post , requests no avail - eg:

request.open('get', url, true); request.onreadystatechange = mycallback; //request.setrequestheader('content-type', 'application/x-www-form-urlencoded'); request.send(null); //tried '' , other data post

my simplest server reply have tried is:

http/1.1 200 ok\r\n content-length: 20\r\n content-type: text/plain\r\n \r\n ...........

i have tried 1.0 instead of 1.1, different headers such connection: close, accept-ranges , other random stuff tried mimic other such responses looked @ wireshark.

obviously must simple magic combination eludes me!

many in advance.

and on note have answered own question cross domain security feature.

which have fixed adding response header:

"access-control-allow-origin: *"

hopefully useful else in future!

(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."
