I have a client that wants our company to set up a link to access directly a secure area in our web site with:
1) only links coming from their site will be accepted (say www.clientssite.com
2) all the logging informatoin has to be in the link and ecrypted
I know it's a two part question & if it gets too complicated instead of splitting the points I could open a second one for part two.
any suggestion to get started?
