RE: Success HttpApi on V4R3
Sender: Scott Klement <klemscot@xxxxxxxxxxxx>
Incidentally, for the sake of testing I'll leave this CGI-script available
for tonight:
http://www.scottklement.com/cgi-bin/test-cgi
It will show you what you're sending to the server... So you can test
with your web browser, and with your HTTPAPI program, and see the
difference.
For testing with a web browser, I used this HTML file to submit it,
based on what you sent earlier:
<head><title>Test Me</title></head>
<body>
<form action="http://www.scottklement.com/cgi-bin/test-cgi"; method="post">
Paste Full Route XML here:
<br>
<textarea name="varPayload" cols="100" rows="50">
</textarea>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>
Then, I cut & paste some XML into that web page, and submit it, and it
shows me how the form is urlencoded... If you can get HTTPAPI to echo
back the same data, you're set... :)
