referrer match and auto expiration
When INTERDUBS client pages need to be guarded against links from specific sites then this can be done via the setting of the configuration: referrer match will auto expire login.
In brief a link on facebook or twitter no longer would be able to expose your content.
Should a visitor click on a link to get to INTERDUBS and the link matches this configuration then the following will happen:
1) The visitor will see an error instead of the page 2) The login will set to expired - no further client access is possible 3) An email is being sent to the creator of the login / reel in question 4) The referring page causing the auto expiration will be noted in the internal login note.
A login expiration can be easily reset via the edit login page.
A reasonable default for this such a setting could be:
twitter facebook bit.ly fb.me goo.gl myspace tinyurl is.gd cli.gs tr.im kl.am ff.im twrl.nl t.co/
Different patterns can be separated by spaces. There is no limit to the number of patterns.
