RSS list not refreshing

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open the RSS window
2. Select one of feeds
3. Get stale result

What is the expected output? What do you see instead?
I should see actual result, instead I see old result, e.g. a week old list of 
values.

What version of the products are you using?
OS:Win 7 SP1, IE11, .NET 4.5
Transmission: n/a
Remote: v3.24 (rev 3)

Please provide any additional information below. Feel free to
attach screenshots or sample code which demonstrates the issue being
described.
I think this is due to WebClient cashing. Changing the URL helps, but only for 
some time. Refreshing the feed with the Refresh button does nothing.

I have "solved" this problem with the following change:
this.Url = url;
-->
this.Url = url + "&rand=" + (new Random()).Next(0, 9999).ToString();
This forces the WebClient to always download the feed as the URL is always 
different. At least as long as I don't run out of numbers :)
