Squid redirector not working with "?" in url

[nitinnitin18]

I configured squid to use redirector behind another squid proxy of our institute.
It is working fine when i am using it to redirect it to another constant url like http://www.google.com/
what i want to do is to redirect each request url as url+?mail, as the proxy server allows all connections
of this type. But it is not working with the perl script

#!/usr/bin/perl
$|=1;
while (<>) {
    @X = split;
    $url = $X[0];
    print "$url\?mail\n";
}

So , i thought that perl might not be working so i wrote an C program for this

int main()
{

    char s[200];
    cin>>s;
    strcat(s,"\?mail");
    cout<<s<<"\n";
}

The redirector script work if i didnt add "\?mail" , actually its the question mark symbol
due to which page is not loaded and it shows an error message of

ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: http://www.google.co.in/?

The following error was encountered:

    * Connection to 74.125.65.104 Failed

The system returned:

    (111) Connection refused

I think its the question mark character which is preventing it from loading as the
page loads if i remove the question mark symbol and add only some character string like "mail".

How can i remove this...
Thanks

These two are not the same. The C++ version has many errors in how it
reads and processes the request, some fatal (2 buffer overflows), some
just causing malfunction (improper reading & parsing of squid requests).

using cin like this is very tricky. Better to read a line at a time and
using string instead of char arrays.

The following C++ should be equal to your perl:

#include <string>
#include <iostream>
#include <sstream>

using namespace std;

int main()
{
    string line;

    while ( getline(cin, line) ) {
        string url;
        istringstream split(line);
        split >> url;
        cout << url << "?mail\n" << flush;
    }
}
