Custom sticky values and multiple tests on a single page

System

Normally, individual creative numbers can be "stuck" by adding sticky=creative_number to the query string (i.e. http://fakesite.com/index.html?sticky=123).

In some cases, such as when running multiple tests on a single page, one may wish to set a different query string parameter for specifying creative numbers. This can be changed at the Subject level under 'Change stickiness'. By default, 'Force sticky request argument' is set to 'optrial.sticky'. To change the parameter to 'sticky2', for example, set it to 'optrial.sticky2' instead. Using this method, we can specify multiple creatives on pages with multiple tests (i.e. http://fakesite.com/index.html?sticky=123&sticky2=321).

Also, you will need to "refresh creatives" after changing the sticky parameter in order for the change to take affect.
