Subject RE: Response->Redirect
Date Fri, 01 Nov 2002 20:52:33 GMT
Hi Brock ,

          Thanks for your reply , I have a main page where i retrieve Query paramters and
pass it on to different .asp pages depending upon choice , I was already doing this
  $start_date = $Request->Param('Start_Date');
  $end_date   = $Request->Param('End_Date');
  $format     = $Request->Param('Format'); and then i was doing this again

my $Sdate = $Server->URLEncode("$Start_Date");
my $Edate = $Server->URLEncode("$End_Date"); , i have removed this it works fine.

         I tried generating Graphs in .asp page , it was clashing with ASP code and generating
error like GD::Graph not declared and few times i would get inconsistent Graphs and hence
reverted to Generating Graph's using Perl.

Regards

Raghu

In your code you should be able to read in the params like this:

  $start_date = $Request->Param('Start_Date');
  $end_date   = $Request->Param('End_Date');
  $format     = $Request->Param('Format');

And you will get the decoded values (i.e. %20 gets translated to a
space, etc.)

...or are you not using Apache::ASP in Graph.pl? What are you using?
CGI.pm module? (should still work...) Can Graph.pl just become Graph.asp?

??
