Its seems that when using the HTMLViewer control, if the URL you request to open contains a redirect, you do not get a DocumentComplete event for the page you are redirected to, only for the page you requested. Am I correct and if so is this a bug?
Bump
Can you post a URL to test against and I will take a look when I get to work tonight… Also, what OS(es) and Xojo version(s) [why does this always have to be asked, it should just automatically be posted when asking for confirmation]

I don’t know what Yahoo is doing exactly, but it is not pure blue.
I loadURL http://yahoo.com
This displays https://fr.yahoo.com/?p=us
Document Complete reports as url https://s.yimg.com/rq/darla/2-8-4/html/r-csc.html
If I put https://s.yimg.com/rq/darla/2-8-4/html/r-csc.html in a browser, I get “undefined document”.
In the UK you probably get something else pertaining to your region.
I think this looks less like a Xojo bug than some hackish trick on Yahoo part to make their pesky geolocalization work.

I think it is a bug. Try other sites, same type of issue
I tried again with a page I built with HTML Refresh.
http://fontmenu.com/xojo/refresh.html
It simply redirects this way :
<META HTTP-EQUIV="REFRESH" CONTENT="2;URL=http://www.matchfonts.com/index.html">The redirect takes forever instead of the 2 seconds set in the HTML, but when the redirect completes, url does report the correct landing one. But the extremely long delay is not normal at all. In a browser, the redirect occurs in a blink.

That’s not the type of redirect that yahoo is using. They are likely returning a 301 or 302 http status code with a URLs in the header to redirect to. The only way I can think of to follow this type of redirect is to use an http socket to request the URL and follow the redirects using the HeadersReceived event until you get back an actual page. Make sure you set the user-agent header in the httpsocket and in the htmlviewer because some sights reject requests if they don’t think you are a browser (or redirect you somewhere else).

I will try your solution. Does the user agent matter, I.e. Do I set it as safari or the like?
The user agent may matter. Sites will sometimes deliver different content based on the browser that connects.
yeah, they are returning 301
