(PHP ActiveX) Debugging with Socket Session Logging

Debugging with socket session logging.

The Chilkat Socket component provides properties for keeping a session log making it possible to see the exact bytes received and sent on a TCP/IP or SSL connection. To enable session logging, set the KeepSessionLog property = 1. The SessionLogEncoding property controls how binary, non-printable bytes are represented in the log. There are two possible settings: Possible values are "esc" and "hex". The default value is "esc".

When set to "hex", the bytes are encoded as a hexidecimalized string. The "esc" encoding is a C-string like encoding, and is more compact than hex if most of the data to be logged is text. Printable us-ascii chars are unmodified. Common "C" control chars are represented as "\r", "\n", "\t", etc. Non-printable and byte values greater than 0x80 are escaped using a backslash and hex encoding: \xHH. Certain printable chars are backslashed: SPACE, double-quote, single-quote, etc.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket')
$socket = new COM("Chilkat.Socket");

// Enable session logging:
$socket->KeepSessionLog = 1;
$socket->SessionLogEncoding = 'esc';

// To demonstrate session logging, we'll connect to an
// HTTP server and download the HTTP response header:
$ssl = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect('www.chilkatsoft.com',80,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->MaxReadIdleMs = 10000;
$socket->MaxSendIdleMs = 10000;

// The socket component includes a BuildHttpGetRequest
// method for convenience. Build a GET and send it to 
// the web server:

$httpGet = $socket->buildHttpGetRequest('http://www.chilkatsoft.com/');

// Send it...
$success = $socket->SendString($httpGet);
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Read the response up to the first double CRLF:
$httpHeader = $socket->receiveUntilMatch('\r\n\r\n');
if ($socket->LastMethodSuccess != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
$success = $socket->Close(20000);

// Display the session log:
print $socket->SessionLog . "\n";

// Show the HTTP response header:
print $httpHeader . "\n";
