i have made a cgi perl program which takes the a sequence and compare it with the other in database...it works well in command prompt but when i link it with html page to accept the sequence through html and print the result in html....when i click the button it opens a window asking"do you want to open or save the program" but didnt run it!!

the html code is
CODE

<HTML>
<HEAD>
    <TITLE></TITLE>
</HEAD>
<script>

</script>

<BODY>
<FORM Action = "c:/perl/bin/p1.pl" Method="POST">

  enter the sequence-<input type="text" name="t1" size=100><br>

<input type="Submit" value="submit" onClick="p1.pl">
</form>

</BODY>
</HTML>

and perl script to get the value from html is as follows:-
CODE

#!/usr/bin/perl.exe
require "cgi-lib.pl";
use CGI qw(:standard);

print "Content-type: text/html\n\n";
&PrintHeader;

A CGI script runs from an HTTP server, not your local computer, although the HTTP server can be installed on your local computer and you can connect to it from localhost. You need to install a server like Apache and then configure it to run CGI script. Use Goggle to find some tutorials to help you.

Your web server is not configured to recognize the script as executable and execute it, so it's sending you the literal content of the document, just like it would for a normal static document.

For Apache, this is controlled by the "ScriptAlias" (to run code within a specific path, such as /cgi-bin/) or AddHandler (to run code with a specific filename extension, such as .cgi) directives. The directory containing the CGI script will also need to have the ExecCGI option turned on (using the "Options" directive) or else you'll get a "permission denied" error when you try to run it.

Dave,

I don't think he has gotten as far as the server install yet :

CODE
<FORM Action = "c:/perl/bin/p1.pl" Method="POST">


The action is pointing directly to a perl script.

Ah, good catch. I assumed an unrecognized Content-Type header since he gets the "do you want to open or save?" prompt, but missed that the POST was going to a path on C: instead of a URL.

1. Do use "require "cgi-lib.pl";".

2. Read Ovid's CGI Course.
