Hi I'm working with Perl to bild CGI web aplications and problems with i think browser cahche. It's a code with +- 2000 lines so i won't post the whole script. But I think the problem is some where in the HTTP header.

First I load the headers and footers from another server using the following:

# User agent object aanmaken
use LWP::UserAgent;
use HTTP::Request;

my $ua = LWP::UserAgent->new;
my $request = HTTP::Request->new<br>('GET','http://www.telfort.nl/inc/
+headers/header_belmobiel.php');
my $response = $ua->request($request);
my $header = $response->as_string();

### Opschonen $header
#my $headtemp;
#($headtemp,$header)= split(/\!/,$header,2);
#$header = "<!".$header;

my $request = HTTP::Request->new<br>('GET','http://www.telfort.nl/inc/
+footers/footer_belmobiel.php');
my $response = $ua->request($request);
my $footer = $response->as_string();

I cut the Headers using split, not elegant but effective.

Then I write my own Header:

print "Cache-Control: no-cache\nPragma: no-cache\n"; ## caching tegen 
+te gaan (speciaal wegens proxy-servers)
    #print $cgi->header;
print "Content-type: text/html\n\n";
  
#### header van telfort #####
print $header;

After this I open a Template to show the content.

If you use the same search parameters in the script it keeps giving different results. If you start with parameters that are wrong it keeps telling the information was not found. Even when you change the parameters to absolute right ones.

Does anyone know the solution or can anyone give me directions to search for solutions. It could be a installation fault on the server but i'm don't have much knowledge of servers and software like apache. Thanx
