http - Open a new tab in a browser with the response to an ASP request -

-

it's bit complicated one... lets have listing of pdf files displayed in user's browser. each filename link pointing not file, asp page, say

<--a href="viewfile.asp?file=somefile.pdf">somefile.pdf</a>

i want viewfile.asp fetch file (i've done bit ok) want file loaded browser if user had opened pdf file directly. , want open in new tab or browser window.

here's (simplified) viewfile.asp:

<% var fileid   = request.querystring ("file") ; var responsebody = mygetrequest (someurl + fileid) ;  if (myhttpresult == 200)     {      if (extractfileext (fileid).tolowercase = "pdf")         {         ??????  // return file contents in new browser tab         }         .... %>

as daniel points out can control whether open in new window not new tab. if user has configured browser new windows should open in new tabs (like do) you're golden. if not open in new window. can't control tabs.

(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."
