How to allow Twitter for one page on the ProxySG

Products

Issue/Introduction

How can you deny limit Twitter access to only one page?

Resolution

VPM Instructions

Specify the following rules in VPM:

1)      Allow the full path to that user in the twitter.com/users/show_for_profile.json?screen_name=USERNAME format and NOT in the twitter/#!/USERNAME format. (twitter/#!/USERNAME is what shows in the address bar and is not processed by the proxy.) Substitute USERNAME with the name of the profile you want to allow. You might want to Allow twitter.com/USERNAME in this rule also.

2)      Deny access to a combined object: twitter.com AND (users OR search).

3)      Allow twitter.com.

4)      Allow referred by twitter.com.

 

 

 

Limitations of this solution:

• This technique has worked with some customers but didn’t work for others.
• When a Twitter page is denied, it doesn’t show an error. It just shows a blank Twitter page.
