roUrlTransfer Request Returns Nothing

I'm having problems receiving a response for one of my REST requests.
Basically, my app is able to parse responses from URLs like this:

But when I add more to the request:
    http://arkbroadcasting.com/rest/play_info.php?video=10&ads=0&prevFillers[]=2000

The debug console shows that I receive no response (not even an error message).

This is the code fragment in question:
' Form a standard request to the server
        mediaLink = "http://arkbroadcasting.com/rest/play_info.php?video=" + calID + "&ads=" + adsID
        
        ' Include the last 10 filler video IDs in request
        ' Including this section of code causes requests to fail when the code is run:
        'for i = 0 to fillerList.count() - 1
        '    mediaLink = mediaLink + "&prevFillers[]=" + fillerList[i]
        'end for
        
        ' Send request to the server and decode response
        mediaRequest = CreateObject("roUrlTransfer")
        mediaRequest.SetURL(mediaLink)
        data = ParseJson(mediaRequest.GetToString())
        
        print "Video Request URL: " + mediaLink
        print "Video Response: " + mediaRequest.getToString()


From my testing, it appears that there is a problem when I add &prevFillers[]=2000 (or the like) to the end of my request URL, but I'm not sure why, or how to resolve the problem. All other requests are served normally for me.
I think it has to do with having [ and ] in the request URL?

Thought I'd include the debug console fragment in question. The two print statements at the bottom of my fragment print these two lines in the first case:
Video Request URL: http://arkbroadcasting.com/rest/play_info.php?video=10&ads=0
Video Response: {"video":"0","filler":"1","filler_id":"7","filler_filename":"1357582161_GettingtoKnowBCF720p.mp4","ads":"0"}
And this in the second case:
Video Request URL: http://arkbroadcasting.com/rest/play_info.php?video=10&ads=0&prevFillers[]=2000
Video Response:

Re: roUrlTransfer Request Returns Nothing

Be sure your URL is properly url-encoded before you call SetURL() on your roURLTransfer object, otherwise SetURL() will fail.

After setting the URL, I like to make a debug call to GetURL() to confirm that the URL actually got set.

xfer.SetURL("http://www.example.com")
? "DEBUG: " + xfer.GetURL()

Re: roUrlTransfer Request Returns Nothing

I'm not sure how to use the URL encode functions. I found a function in the documentation:
http://sdkdocs.roku.com/display/RokuSDK ... eStringurl
But I couldn't get it to work properly

However, through further research, it seems my problem was that I need to use %5B to encode [ and %5D to encode ]. Changing the URL to use this URL encoding fixed my problem.
Therefore, the URL was changed to:
http://arkbroadcasting.com/rest/play_in ... rs%1B%1D=7
