I would like to send a link to a user (via email) that expires after a period
of time.
When a user takes a certain action, they are emailed a link that allows them
access to a certain resource.
What I want to do is make it so that the link will work for a period of time
(say 48 hours) and then will
no longer work. I would like the link to look like:
http://www.mysite.com/stuff/b39a8b314588d04e23f15ceb026196c5
or
http://www.mysite.com/stuff/resourcea?b39a8b314588d04e23f15ceb026196c5
Rails would need to decrypt the url (it doesn't need to be cryptographically
secure, but it
should be non obvious), determine if the timeframe is still valid and serve the
resource (or not).
I would rather that the timeframe be included in the link instead of having to
do a db lookup.
Are there any gems/plug-ins out there for this? How would I go about creating
it from scratch?
