What breaks AlfaBB links to eBay auctions ?!?
When I started this thread, I learned that eBay or a service AlfaBB is using dynamically replaces correct links to eBay auctions with a link to a "This listing () has been removed, or this item is not available" error message from "rover.ebay.com."
Example:

I'm sure other AlfaBBers are encountering this problem also. Does anybody know why the referral links are blocked?

Example:
I double checked my original post and found it contains a correct and valid link to an active auction listing (which is easily verified by using the "Quote" button for a message). The URL replacement happens dynamically in the browser, not on the server. However, I don't think the problem is browser dependent (I'm using the latest Firefox with Adblock Plus).

I certainly don't know the answer, but this may explain why when people send me eBay links through e-mail, which then open in my Firefox browser, when I click on them they are blocked or give a 404 page error. It leads me to believe it's possibly an eBay security feature or something on their end.
It's a royal PITA to have to go back and try and find the item that the link should have provided.

The following three links show different link format eBay uses. The first link is a bare-bones link to an item. The second link is for to the same item after the eBay search function is used to find the item by auction number. The third link shows the link that results from an item search by name.
Code:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=150385705673
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=150385705673&ru=http%3A%2F%2Fmotors.shop.ebay.com%3A80%2F__%3F_from%3DR40%26_trksid%3Dm39%26_nkw%3D150385705673%26_fvi%3D1&_rdc=1
http://cgi.ebay.com/ebaymotors/Chrysler-IMPERIAL-FAMILY-CHRYSLER-SERIES-72-RUN-DRIVE-CONDITION-GOLF-EDITION_W0QQitemZ150385705673QQcmdZViewItemQQptZUS_Cars_Trucks?hash=item2303afc2c9
If you have problems with broken URLs arriving via e-mail, you can try extracting the auction number from the string (the item number is embedded in the string between "itemZ" and "QQcmd" -- I believe eBay substitutes "Z" for the equal sign "=" and "QQ" for the ampersand "&").
What's happening on AlfaBB is different in the sense that the original link gets replaced. My original post used the first link above but it was changed to this one:
Code:
http://rover.ebay.com/rover/1/711-53200-19255-0/1?campid=5335827019&toolid=10001&mpre=http%3A%2F%2Fcgi.ebay.com%2Febaymotors%2Fws%2FeBayISAPI.dll%3FViewItem%26amp%3Bitem%3D150385705673
I'll need to do some more investigation (capture TCP traffic) to determine for sure whether this happens in the browser or on the server.

I think I know what's causing this, and I've been confused (now and then) by that particular feature of alfabb.com before. Ever noticed how the BB apparently visits any URLs you add in a message and puts the page title in the message url token?
I.e. a link to NY Times pasted directly into a message yields The New York Times - Breaking News, World News & Multimedia without me doing anything to make the link that pretty.
The real URL for the Chrysler mentioned above actually contains two URLs, where the last one probably is a reference to what part of eBay the listing was originally entered (motors.shop.ebay.com in this case), and I think the software here at AlfaBB gets confused because of that.

When you hit the "Quote" button, the original link you posted appears in the quoted text (probably pulled from the AlfaBB database) without being made "pretty". Now, I'll try to find out if the links get changed when the AlfaBB server creates the output, or if it happens in the browser.

Something not right here. I'll have to review this later and get back to you guys why these links are getting busted.

Ruedi,
We do run a eBay scrip on our end that does change eBay URLs dynamically but I'm not sure why particular ones are getting busted and others are not. Stay tuned.
