Hi , I have written a sample perl program (sample.pl) to fetch all the environmental variables of my system. I put this into cgi-bin folder of my apache . then i fetch the page using "http://11.11.11.11/cgi-bin/sample.pl"; in my machine so when i hit the url , i get the above output on my webpage.
i send the same url in my curl application and try to fetch the output as shown above.. i hope i didnt confuse the matter the same url i am passing to curl On Tue, Nov 19, 2013 at 7:34 PM, Fahad Ashfaque <[email protected]> wrote: > The "Sample output" at the end of your message is actually the HTTP > Request that *you* are sending to the server...
