Passing data between frames after one frame loaded by Perl

I'm looking for a solution;
In developing a site using frames, passing data from different html pages in frameset works unless a page is created by a Perl script.

example method to pass data is simply :
used in LEFT by javascript "top.right.document.rightformname.mydata1.value=1;"
and used in RIGHT by javascript "top.left.document.leftformname.mydata2.value=2;"
Other methods may us IDs, etc... not a problem.

HOWEVER,

if frameset has framename=LEFT src=left.htm
and framenameright=RIGHT src=right.htm
the passing of data between pages works.

if framename=LEFT src=left.pl and the Perl script writes(prints) the exact same html code as the static page, the passing of data with right.htm will not work.

Something is broken when the page is generated or loaded by a script rather than just opening a static page.
I can't find any reference info to explain why.

Help anyone?

Please be kind, I'm trying to solve a real problem.

The functional HTML page source was copied into
a Perl script sub routine such that it prints it verbatum. This is well understood and hasn't been a concern;

###
sub Printapage {

print "Content-type: text/html\n\n";
print <<EOP1;

<html><head>
<META content="text/html; charset=iso-8859-1" http-equiv=Content-Type>
<TITLE>frame 1 page</TITLE>
</HEAD>
<BODY>
<form name="datum" method=post action="http//blahblah.com/blah/blah.pl">

<input type=hidden name="item1" value="123">
<input type=hidden name="item2" value="456">

</form></body></html>
EOP1
}

###

within another frame, frame2, a javavscript grabs
, on an event, the values of item1 & item2 using the DOM.
ex.
document.TESTFORM.INPUT1.value=parent.frame1.document.datum.item1.value;

This works fine when html pages are initially loaded into the frames, however the DOM seems broken if frame1 loads as referenced a Perl script to write the page instead of a static page.

I read a snippet of info at MS that Windows XP SP1 to SP2 upgrade affect the "cache" in IE such that frames may loose their identity (this being a security measure). Rather than blaming MS for their obvious stupidity in many things, I thought someone may inderstand this and have a work-around.

Thanx,

The resultant discovery is;
IF the calling webpage is resident on a PC
and it loads some frames with local PC(client) pages
and others from the server, the FRAMES lose their ID
or the local versus server pages cannot find the frame ID.

I've experimented numerous times and the upshot is;
all pages in frames must all come from same source
(server or local) else the passing of data between frames (or windows) is prevented.
I suspect that IE appends to the ID the location the page was got from.

I haven't found a distinct reference anywhere, but
this may be useful info for others looking to make
combined interfaces that are both local and from the server.
