My best guess is you can’t… it is it possible to bypass a page redirect that a server does internally?
Trying to list a vehicle on Autotrader.com…and the main sell my vehicle page won’t accept the VIN as valid…probably because it’s technically a commercial VIN even though it’s not used as a commercial vehicle. I asked their support the other day and they sent me a different url…tried it on my iPad Friday and that page accepted the VIN…but didn’t finish the ad that day. Tried again today on iPad and Mac and pasted the good url into Safari and Firefox…and it redirects to the main sales page that doesn’t like the VIN.
I sent another email to them asking what the heck…but in the interim wanted to make sure there’s no “don’t redirect this” trick that I don’t know.
