Due to the same origin policy you aren't normally able to request resources from a different domain.  Try adding crossDomain: true to your AJAX request since you are trying to make a request to a different domain.

$.ajax({
    url: 'http://my.domain.tld/cgi-bin/myPerlScript.pl',
    crossDomain: true,
    data: "lastID=" + lastID
       + '&amp;qkz=' + Math.random(),
       dataType: "json",
       success: JSONreceive,
       error: JSONerror

I've been trying to figure out what I should use when cleaning my bicycle chain.  When I first purchased my bike, I knew I needed to lube my chain when i did regular maintenance.  I purchased some White Lightning Self Cleaning Bicycle lube, which suggested to me that I only needed to put that lube on the chain and everything would be fine.  

I recently purchased another brand of lube, and it didn't say anything about self cleaning.  I've read in several places that a degreaser is needed and a cloth and some soap to clean a chain properly, and then lubing takes place afterwards.  

If I buy White Lighting self cleaning lube, do I need to go through the regular chain cleaning steps?  or can i just lube my chain and go?
