 * Hi
 * Thanks for such a good plugin.
 * I would like to know how “refresh interval” option works?
 * Does it connect to the server to check the page in N milliseconds each time or
   it’s happening only in the user’s browser? (Actually I want to know if it makes
   a server load issue or not).
 * Thank you.

 * Hi,
 * I have seen a noticeable increase of CPU load (>4% rather than 0-2% without the
   plugin) when the “refresh interval” is set to something different than zero.
   
   So, I decided to set it back to zero to avoid a useless CPU load on the client’s
   side.
 * Meanwhile, I have found this explanation that could be of interest for you :
 * “Refresh Interval defines (in milliseconds, 1 sec = 1000 ms) how often plugin
   recalculates sticky widgets parameters. Required by sites with dynamic content(
   infinite scroll, image lazy load and other javascript stuff). The option have
   impact on the site performance (client side). Recommended values: 250 — 1500 
   milliseconds. If you don’t have dynamic content, set Refresh interval = 0”
