    In this case the problem is that the windows scripting host consumes the double quotes included in the arguments.

    npocmaka has shown one of the solutions: encode the quotes in the url. From my point of view it is the correct one (double quote is an unsafe character and should be encoded).

    Another solution is to not to pass the URL as an argument to the script, but to store it in a environment variable and then in the javascript part retrieve the value from the variable

    @if (@This==@IsBatch) @then
    @echo off
    rem **** batch zone *********************************************************
    
        setlocal enableextensions disabledelayedexpansion
    
        rem Ensure we get a correct reference to current batch file
        call :getFullBatchReference _f0
    
        rem Batch file will delegate all the work to the script engine 
        if not "%~1"=="" (
            set "URL=%~1"
            cscript //nologo //E:JScript "%_f0%"
        )
    
        rem Ensure batch ends execution before reaching javascript zone
        exit /b %errorlevel%
    
    :getFullBatchReference returnVar
        set "%~1=%~f0"
        goto :eof
    
    @end
    // **** Javascript zone *****************************************************
    // Instantiate the needed component to make url queries
    var http = WScript.CreateObject('MSXML2.ServerXMLHTTP.6.0');
    
    // Retrieve the url parameter from environment variable
    var url = WScript.CreateObject('WScript.Shell')
                .Environment('Process')
                .Item('URL');
    
    var exitCode = 0;
    
        try {
            // Make the request
            http.open("GET", url, false);
            http.send();
    
            // If we get a OK from server (status 200), echo data to console
            if (http.status === 200) {
                WScript.StdOut.Write(http.responseText);
            } else {
                exitCode = http.status;
            };
    
        } catch (e) {
            // Something failed
            WScript.StdOut.Write('ERROR: ' + e.description );
            exitCode = 1;
        };
    
        // All done. Exit
        WScript.Quit( exitCode );
    

    Now, it can be called as

    geturl.cmd "http://gatherer.wizards.com/Pages/Search/Default.aspx?output=spoiler&method=visual&action=advanced&set=["Arabian+Nights"]"
