IE7 Cookies not persisting. Please help

I’m new to cookies and rails so I apologize for my ignorance. I’m
using Javascript to store persistent cookies using the following code
(taken from the O’Reilly Javascript book):

Cookie.prototype.store = function( daysToLive, path, domain, secure )
{
var cookieval = “” ;

for ( var prop in this )
{
// Ignore properties wiht names that begin with the ‘$’ and also
methods
if ( ( prop.charAt(0) == ‘$’ ) || ( ( typeof this[prop]) ==
‘function’ ) )
continue ;

if ( cookieval != "" ) cookieval += '&' ;

cookieval += prop + ':' + encodeURIComponent( this[prop] ) ;

}
var cookie = this.$name + ‘=’ + cookieval ;

if ( daysToLive || daysToLive == 0 )
{
cookie += “; max-age=” + (daysToLive2460*60) ;
}

if ( path ) cookie += “; path=” + path ;
if ( domain ) cookie += “; domain=” + domain ;
if ( secure ) cookie += “; secure” ;

// Now store the cookie by setting the Document.cookie property
document.cookie = cookie ;
}

This works fine in Firefox but in IE7 it seems to work like a session
cookie. As soon as I close the browser it doesn’t exist.

I’m certain it’s something in Rails that I’m missing.

Thanks in advance for the help!

A few more details:

  • I don’t have any other cookies for the domain
  • There is not an underscore in the domain/subdomain
  • My privacy setting are at their lowest (accept all cookies)
  • The cookie is there and accessible until I close the browser and
    restart
  • I’m sure there’s a simple Rails reason for all of this. I don’t
    want to have to persist the session to make this work, is that even
    possible in Rails?

Thanks again.

Try the depricated expires attribute instead of max-age, which is not
supported by IE. expires differs from max-age in that it sets a date
(UTC) instead of a duration.
