OT: shortening eBay URLSs (Was: IBM PT-2

[Fred Cisin]

That is useful information.

I had explicitly givien the shortest URL that I found to work.  Others 
pointed out that the auction NUMBER is the important piece of informtion, 
and that the rest to make a URL can be recreated.

I suppose that somebody with some time on their hands could/should go 
through and document more of the fields in the eBay URL structure.

I think I tried removing one or more and it stopped working, but I was not systematic, since, well, I didn't really care.  This is what I use in the show notes of the Retrocomputing Roundtable episodes, since odds are good that auctions we talk about there will have ended by the time people try the links.  In the context of cctalk, this might be useful for pointing to auctions that are interesting to look at, rather than to auctions that people might want to participate in (since in that latter case, ended auctions stop being interesting).
