Check if url set on metatrader

[fabiobioware]

I want my EA to check every 15 minutes if there is communication with a website.

My EA sends information to a google spreadsheet, I would like every 15 minutes to check whether the url google.docs.com is added to the list of urls on the metatrader.
If not, the EA must be removed from the chart immediately.

I saw several EA have to enable the use of url or dll, I want the same function in mine.
