How to call a simple perl script from HTML without need of HTTPS but simple HTTP ?

[Wladimir Borsov]

I want to call a perl script myscript.pl in my cgi-bin from a HTML web page.
This call should NOT use SSI (because in this case HTTPS://.... protocol is necessary).
Furthermore NO button click should be required (so I am not talking about a perl script in a form).

I only want to call this script automatically when someone load the web page.

How can I do this ?

If necessary the perl script could return a value (e.g. a picture resp. text string) to the calling page.

SSI? SSL? I can only guess, but I assume that the document URL must be
accessed with HTTPS and the script must be accessed with HTTP.

If you really want the script *always* to be executed, the only option is
that the script *is* the document. Use mod_rewrite or similar techniques,
so the script is called when the document URL is requested, let the script
perform whichever task it should do and let it finally return the document
(including correct HTTP headers). But this does not fit with your first
requirement above (if my guess was right).

If it is sufficient that the script is only executed in many cases, when
(probably) a human with a graphical UA requests the document, 'embed' the
script as a IMG element and make it return e.g. a 1x1 transparent GIF.
(This is a so-called 'web bug' and some people don't like these and use
filters to get rid of 'em).
Just use a absolute URL http://.../cgi-bin/script.pl and it's requested with
HTTP, even if the document URL is https://...

If necessary the perl script could return a value (e.g. a picture resp.
text string) to the calling page.

At it's simplest.

It's simpler than possibility: it isn't even valid markup. As soon as
you consider writing an alt attribute, you will (hopefully) stop and
think what should and could be done when the user agent does not
automatically load an image. Note that the user agent might decide not
to load the image even if it is a common visual browser with automatic
image loading disabled, since it notices that the image is already in
its cache (and it might also get it from a proxy cache).

Thus, this rolls back to the question what the original problem is.
Automatic execution of a server-side script sounds like one possible
approach to solving some problem - which?

It is surely much more robust to arrange things so that the page's
address refers to a server-side script. This script can then do whatever
is necessary before sending the browser some HTML document (perhaps
something that the script just picks up from a file). Even then, caching
may complicate things.

There is the "onload" attribute for <body>. But that is only useful if
the script does no output.
It depends on what the script does.
- Does it modify the HTML in any way?
- Does it output any text?
- Does it only update some information in the background?

It causes a _client-side_ script to be executed, when client-side
scripting is enabled. The question is about server-side scripting.

Create an image and set its source to your script.
Or use xmlhttp.
