I am using perl to create some phone services.  I have created one that will go out to the web to get an image and convert it to the CIP format to be displayed on a phone.  This part is working correctly.  I would like to have the service refresh every few minutes so the image stays up to date.  Here is the code I am using to create the header:
my $q = CGI->new;
print $q->header(-type=>'text/xml',-Refresh=>'10');
 
When testing in a web browser this makes the page refresh every 10 seconds as expected, but on the 7961 I am using to test it does not refresh.  Is there something I am missing about creating the header for something like this?

I added a -url with the exact URL that needs to be refreshed, but the phone was not able to auto-refresh.  Is there something wrong with the way I am constructing the header?

I grabbed a capture of traffic going to the phone as well as my laptop.  In the capture for the phone I was able to see the url and refresh settings for the other page that is working, but the new page I am trying to create did not have either setting.
 
However, in the capture for my laptop the same page had the url and refresh settings in the http header.  It seems for some reason when my page is being sent to the phone those settings are being stripped out or lost.
