Question

I’m having a problem with a youtube cache I’m trying to make (my internet connection is really slow). It works by detecting if a videoplayback page is requested and saves the response to the disk. It works fine with lightspark and the html5 player on FireFox, but when I try it on Google Chrome I get a Write Failure in RespCacheCallback.

I have the source here as it is too long to be posted with the question.

I forgot to add the range to the ID created in the program when I searched the cache, which meant that the program tried to send the entire video when a small portion was requested, which made the player close the connection. That was fixed by adding this method to MainClass

static bool TryGetRange (string url, out string range)
{
    int index = url.IndexOf ("&range=");
    if (index == -1) {
        range = null;
        return false;
    }
    index += 7;
    int len = url.IndexOf ('&',index) - index;
    range = url.Substring (index,len);
    return true;
}

This method checks if the range parameter is present in the url, and then gets the value of it.
Then adding this code before if(File.Exists (requestData.Signature + "_done"))

string range;
if(TryGetRange (requestString, out range))
{       
    requestData.Signature += range;
}

This adds the range to the signature if the range parameter is detected
