Is there a way to run a Perl script WITHOUT submitting a form? I want to be
able to click an "update" button on a page and have it run a Perl script to
update info, without changing the document in the browser. Is there any
way to do that and leave the current page intact in the browser?

Thanks!

Change the source of an image to point to your Perl script. When its
requested from the server, it executes the script. Either hide the image
or have the perl script return a harmless image.

That is a cute way to do it... you can hide the image in a div with
visibilty turned off... I like it.

My idea is to hav a small (1x1) IFRAME that changes source.

That works, in browsers that support IFrames (Its the NN4.xx in me
coming out). Hence my suggestion for the images. Image swapping has to
be more widely supported than IFrames.

Let your Perl script return the HTTP response code 204 and the browser
shouldn't change anything, no need for scripting.

What kind of header goes on that? Do I use the HTML "Content-type:
text/html" header before sending it? (Obviously I've never used error
codes before.)
