Mystery for the day... WTF is W0QQ?

...sometimes non-coders pose the darnedest questions.

My housemate today asked me why "all the URLs on shopping sites suddenly have W0QQ at the end of them?"

To this, I had to say "I have absolutely no clue" and, curiosity peaked, I am afraid to say twenty minutes later I still have absolutely no clue. You can't really google it -- you'll be saturated with results. Those few places I found it embedded in code were dead ends.

So if you're bored and up for a worthy challenge, try this one out.

What the heck is w0qq?

1. Shopping sites or eBay?
If you visit eBay, it looks like they use GET submissions, but don't use the usual '?' and '&' query and data delimiters. Instead, they mark the start of the query with 'W0QQ' and break up the data with 'QQ'. Why, I don't know.

Try this search string:

http://home.search.ebay.com/candle_Candles_W0QQsacatZ16...

and mouse over the URLs from the returned items and you'll see stuff like this:

http://cgi.ebay.com/A-FULL-DOZEN-CUSTOM-Grubby-Bakery-T...

2. Its a technique of passing data
W0 demarcates the start of data and the QQ is a delimiter (think about it, can you imagine an instance where a word or a piece of data would have two capital Q's next to each other?).

3. Sure, what I mean is...
What are the origins. Is it particular to a specific inhouse application, commercially available codebase, or programming/markup language? Who picked that string and why?

If it's an in-house thing we'll probably never know, but I figured someone might have fun trying to figure it out.

Pretty funny, it's already in Google's dictionary -- if you search for a similar non-used string it will correct your spelling.

4. The W0 is weird, but the QQ does make sense to me.
