[mod_python] Cookies not persisting

Thu May 10 14:39:31 EDT 2007

I am trying to fiddle around with AJAX but before I can get to that part 
I need to make a little test login system will automatically log the 
user in if a cookie is found. The problem is when I close the browser 
the cookie is deleted. Everything else should work (when I click the 
logout button I am still staying logged in because it found the cookie). 
Does it have something to do with my browser or an attribute I am not 
setting when I create the cookie.

Thanks,
Ryan

below is the code:

import time
from mod_python import util
from mod_python import Session, Cookie

username = "test"
password = "pass"

main_page2 = """
<html>
 <head>
  <title>Main</title>
 </head>
 <body>
  Welcome!
  <p> <a href=\"./logout\">Logout</a> </p>
 </body>
</html>
"""

login_page = """
<html>
 <head>
  <title>Login</title>
 </head>
 <body>
  <h1>Please login</h1>
  <form action=\"./login\" method=\"POST\">
   Username <input type=\"text\" name=\"user\"/> <br/>
   Password <input type=\"text\" name=\"pass\"/> <br/>
   Remember me? <input type=\"checkbox\" name=\"remember\"/> <br/>
   <button type=\"submit\">Login</button>
  </form>
 </body>
</html>
