how to launch a URL link in script task using C#

I have a URL, for example, "https://www.google.com/" I have a http connection manager for the URL set up in a ssis package. 

Now I want to just launch the link, NOT downloading any data or saving any data in files from that link. In real scenario, the link I use is to clean the cache after processing... 

Anyway, I don't know how to write the C# code, or are there any other ways to call those links INSIDE a ssis package? 

PLEASE HELP!!
