I want to get ALL parameters of GET method and put them together in a single string variable...

ex.

If Test.pl?a=1&b=2&c=3&d=%20Test%20 called

I want to have a=1&b=2&c=3&d=%20Test%20 in a single string variable in same format with & and html encoded.

Thanks from now!

You could just get the $ENV{QUERYSTRING}, and this would be exactly the querystring to your script.

I want URL and parameters all together

I mean:

http://www.mysite.com/test.pl?a=1&b=2&c=3&d=%20Test%20

I want entire URL

There isn't a method to get it dynamically?

The REQUEST_URI will not contain the protocol (http), or the domain (www.mysite.com).  And if the current page is different from the desired link, it will not be correct.

What do you want to get?  There are several environment variables that contain different parts of what you are asking for.

Here are some environment variables that might help with what you want:
SCRIPT_NAME   - The name of the script as seen by the web browser (eg: /test.pl)
SERVER_NAME   - The hostname (eg: www.mysite.com)
QUERY_STRING  - The part after the question mark (eg: a=1&b=2&c=3&d=%20Test%20)
SERVER_PORT   - The port, part after the colon of hostname, or 80 if not specified
REQUEST_URI   - "$ENV{SCRIPT_NAME}?$ENV{QUERY_STRING}"
HTTP_HOST     - "$ENV{SERVER_NAME}:$ENV{SERVER_PORT}"

apache. Not sure what version the webhost is using. It gives me the full url MINUS the querystring!

I'm using apache 2.2.8, which looks to be the newest release.... wondering if SCRIPT_URI is a non-standard add-on your host is using.

Partial quote from http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html
(SCRIPT_URI is probably documented elsewhere, but that was the first google hit)
This module keeps track of two additional (non-standard) CGI/SSI environment variables named SCRIPT_URL  and SCRIPT_URI. These contain the logical Web-view to the current resource, while the standard CGI/SSI variables SCRIPT_NAME and SCRIPT_FILENAME contain the physical  System-view.
 
Notice: These variables hold the URI/URL as they were initially requested, that is, before any rewriting. This is important to note because the rewriting process is primarily used to rewrite logical URLs to physical pathnames.
Example
 
SCRIPT_NAME=/sw/lib/w3s/tree/global/u/rse/.www/index.html
SCRIPT_FILENAME=/u/rse/.www/index.html
SCRIPT_URL=/u/rse/
SCRIPT_URI=http://en1.engelschall.com/u/rse/

With 2.2.8.... I meant 2.2 is the latest - there is a 2.2.9 released on 2008-06-13, but I doubt this would have changed.
