Hi!
I, like many others, are trying to login to a website using HttpClient and
the PostMethod. When running the program I'm getting the following result:
Login form get: HTTP/1.1 200 OK
Initial set of cookies:
- PHPSESSID=4c3499e030f2e09c35e5af6fb20571f0
- checksum=f2d870271e0887c854fd041ad746cb78
Login form post: HTTP/1.1 200 OK
Logon cookies:
- PHPSESSID=4eb20a61a4a09f4cf89db46af25affb2
- checksum=0a8a452f089ad78ce3b0ea670d0d8011
And since I'm not very familiar with either php or cookies I really don't
know what to do next. I actually expected to get some kind of redirect or
something, but now I don't get anything like that, so basically I need some
help on what to do next.
I'm not really sure i got the NameValuePairs correct either...
Here's the page source from the website for the form;
<form method="post" action="takelogin.php">
<p>Note: You need cookies enabled to log in.</p>
<table border="0" cellpadding=5>
<tr><td class=rowhead>Username:</td><td align=left><input type="text"
size=40 name="username" /></td></tr>
<tr><td class=rowhead>Password:</td><td align=left><input
type="password" size=40 name="password" /></td></tr>
<!--<tr><td class=rowhead>Duration:</td><td align=left><input
type=checkbox name=logout value='yes' checked>Log me out after 15
minutes inactivity</td></tr>-->
<tr><td colspan="2" align="center"><input name="login" type="submit"
value="Log in!" class=btn></td></tr>
</table>
<input type="hidden" name="returnto" value="/" />
</form>
Any help is highly appreciated. Please guide me, I am in need of help.
Thanks
Mathias
