At present in the Internet there is practiced protection from excessive website overload caused by users. The point of the protection is the following: if there are very many simultaneous requests on getting the page from your IP address, you overload this server (DoS attack). Thus your IP server is blocked and you stop getting the contents.

We have a mechanism which will decrease the load on such websites. You can set your own EmEx 3 options such as the number of simultaneous requests, the download time period for selected website, etc. When the limit will be exhausted, EmEx 3 will wait before addressing to this website again.
