Yikes! NO! You can't just overwrite the string returned by
match->getURL(), as you're doing with strncat(), because you have no idea
how much extra memory is available in the string. I haven't tested this,
but I think what you want is something more like:
char *url = match->getURL();
String *new_url = new String(url);
*new_url << "?track=00101.00015.005.00012.001-99010613001212638";
vars.Add("URL", new_url);
