last modified challenge!!

[kevin_huinink]

I want an HTML document to
dynamically post the 'last modified' date of another document on the
Internet.
eg. I upload our newsletter.pdf
The News page with a link to the pdf should read
"This file last updated/uploaded on ___________"

Possible?

Please read the posting guidelines - http://www.codingforums.com/postguide.htm - specifically the bit about choosing an appropriate title. Baiting for answers by dressing up your question as a "challenge" usually has the opposite effect from what you intended.

As to your question - no, you can't read the last modified date of an external document with javascript. But a server side language could do it.

Well, brothercake, yes and no. If the target file is on another domain, you're right. And if it's any type of file not normally displayed by a browser, you're right. But:

 PopUp1=window.open('target.htm','x');
 LM=PopUp1.document.lastModified;
 alert(LM);
 PopUp1.window.close();

Never being one to leave well-enough alone, I had to expand upon the above:

 function GetLM() {
   Targets=new Array(
     'target1.htm',
     'target2.htm',
     'target3.htm',
     'target4.htm'
   );
   PopUp1='';
   Message='';
   ix1=-1;
   AddLM();
 }
 function AddLM() {
   if ((PopUp1) && (!PopUp1.closed)) { PopUp1.window.close(); }
   ix1=ix1*1+1*1;
&nbsp;&nbsp;&nbsp;if&nbsp;(ix1*1&nbsp;<&nbsp;Targets.length)&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Target=Targets[ix1];
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Opts='width=100,height=100';
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;PopUp1=window.open(Target,'x',Opts);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;this.window.focus();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LM=Target+':&nbsp;'+PopUp1.document.lastModified;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Message+='\n'+LM;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TimeOut1=setTimeout("AddLM()",500);
&nbsp;&nbsp;&nbsp;}&nbsp;else&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;alert(Message);
&nbsp;&nbsp;&nbsp;}
&nbsp;}
