in thread How do i refresh a page from the perl script.

Hi there thanks for the response. let me be more clear with my problem. I have a pure html page(not cgi). I have 3 buttons on it. first one is the submit and the second one is of type button and the third one is of type button. so the second one is calling the perl script. now this perl script does somethig with parameters i pass. and then gets back to the original page with : 
print "Location:http://mypage.html \n\n";

but the thing is it doesnot refresh the page so all the fields are gone. Is it possible to just refresh a page from perl and not to restart the whole page again. thanks - anjaana

    The answer to the direct question is "no", and that has more to do with the way HTTP and web browsers work than Perl. In general, a web server doesn't normally send just part of a page to replace an existing page. There are ways to do this with JavaScript and other client-side programs as well as with multipart transfers. That's probably not what you want.

    A simpler explanation is to generate the HTML page within the CGI program. You'll send the whole thing to the browser, but you'll have the opportunity to substitute in your preferred parameters. If you follow this road, you might end up coding the whole thing as a Perl program, integrating the static HTML page into the program or as a template or something. If there are no parameters passed (that is, the user pressed no buttons, just loaded the page for the first time), send a blank form. If the user pressed a button, perform the appropriate action.

    Doing much of anything else makes a lot of assumptions about the web browser. In some cases, you can get away with that.
