    I've installed Fiddler on my Windows 7 machine and I'm trying to execute the following PHP CURL routine so that I can see the POST request body in Fiddler:

    01.$proxy = 'http://localhost:8888';
    03.$ch = curl_init();
    04.$curlConfig = array(
    05.    CURLOPT_URL             => "http://localhost/projects/curl_1/test.php",
    06.    CURLOPT_POST                    => true,
    07.    CURLOPT_RETURNTRANSFER  => true,
    08.    CURLOPT_PROXY           => $proxy,
    10.    CURLOPT_POSTFIELDS      => array(
    11.        'test1' => 'blah',
    12.        'test2' => 'more blah',
    13.    )
    15.curl_setopt_array($ch, $curlConfig);
    16.$result = curl_exec($ch);

    Whenever I visit the page, however, all I see in Fiddler is a GET request--not a POST request.

    What do I need to do / configure in Fiddler to see the POST requests? I don't have the HTTPS Decryption enabled but that's because I shouldn't need to enable it for basic HTTP debugging (I'm not working with any SSL projects at the moment).

    Hello, Casey--

    You're seeing the GET request from your browser, and not seeing the request from the backend server process.

    The likely problem here is that you've set CURLOPT_HTTPPROXY_TUNNEL which could be named CURLOPT_DO_NON_STANDARD_CRAZINESS_AND_DONT_USE_PROXY_PROPERLY.

    Unset that option.

    If you're still having problems, try leaving the option unset and change the target URL to Do you see the request then?

    Eric, your first suggestion did it. I'm FINALLY seeing POSTs! Thank you so much!

    (And major props for the quick response.)
