SPUG: Forcing a browser to refresh a file

[Richard Wood]

Thanks for the ideas, 

I was letting my uncertainty about what headers to
send keep me from just sending the XML file to the
browser in the message.  I fooled with it briefly and
got it working.  All I had to do was

print "Content-type: text/xml\n\n";

in front of the xml and it worked just fine!

Thanks for the help!

FYI, the application sends 500 rows of 6 columns of
data to the browser.  The user can then sort the data
on any column.  If they click on a cell, the row opens
up for update.  If they change data, the changes are
submitted for update and then the data is returned
with the next selected row opened for update.  All of
the sorting and opening of form fields are done with
XSL.  Pretty cool and all client side.
