Hi everyone,
Hopefully I am sending this correctly, it is the first
question I have sent.
I believe this to be trivial (for someone), but I
can't find the answer.
I am building an XML file in a perl script. I then
print location and content headers to direct the
browser to the xml file. The problem is, the browser
is picking up a cached version of the file. What can
I do (from the server's perspective) to force the
browser to refresh the file? I suspect it is
something in the headers I send, like the date for the
file. But I can't get anything to work (yet).
Here are some bits and pieces from the code:
my $redirect_string = "http://myhome.com/table.xml";
($RT,$WT) = (stat("table.xml"))[8,9];
$tm = localtime($WT);
$hdate = sprintf
"%4d%02d%02dT%02d%02d%02dTZD",$tm->year+1900,
$tm->mon+1, $tm->mday, $tm->hour, $tm->min, $tm->sec;
print ("Location: $redirect_string\n");
print ("Date: $htmldate\n");
print ("Content-type: text/xml\n\n");
Regards,
Rich Wood
