873616 - Grand Hyatt Taipei website redirects to 404 on a server-not-found, on Firefox (and Chrome, and Opera Mini) on Android

Status: RESOLVED FIXED

(Web Compatibility :: Site Reports, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Visit http://taipei.grand.hyatt.com/en/hotel/home.html using Firefox Nightly on a tablet, or in a desktop browser with this overridden user agent string:
  Mozilla/5.0 (Android; Tablet; rv:24.0) Gecko/24.0 Firefox/24.0

ACTUAL RESULTS: I get redirected to this URL:
 http://m.mobilehyatt.com/mt/taipei.grand.mobilehyatt.com/hyatt/404.jsp
*and* there's also nothing at that domain -- I hit "Firefox can't find the server at m.mobilehyatt.com" -- so I don't even get to the 404.jsp page.

I tested this using:
* Nightly on my Nexus 7 Android tablet
* Nightly and Firefox Beta on my Nexus 4 Android phone
* Chrome on my Nexus 4 Android phone

and I got the same (bad) results in each.  (So this isn't a Gecko-specific thing -- chrome on mobile devices hit the same problem)

Attachment: pruned curl log, showing series of redirects

I ran a series of
  curl -v -A "Mozilla/5.0 (Android; Tablet; rv:24.0) Gecko/24.0 Firefox/24.0" 
commands, to trace the series of redirects. These show that we're bounced from
 http://taipei.grand.hyatt.com/en/hotel/home.html
to:
 http://m.hyatt.com/mt/taipei.grand.mobilehyatt.com/en/hotel/home.html
to:
 http://taipei.grand.mobilehyatt.com/en/hotel/home.html?stop_mobi=yes
to:
 http://m.mobilehyatt.com/mt/taipei.grand.mobilehyatt.com/hyatt/404.jsp
...and m.mobilehyatt.com doesn't resolve.

Here's a log showing those curl commands and their output (just up to the "Location: " line for brevity).

[I tested Opera Mini on my Nexus 4, too, for good measure -- same results.]

I just sent this message to the email address on their website, [e-mail] :

Dear Grand Hyatt Taipei,

(Whoever receives this: please forward this email to a web developer or
admin who's involved with your English website,
http://taipei.grand.hyatt.com/en/hotel/home.html )

Hi! I'm a browser developer working on the Mozilla Firefox web browser,
and I wanted to let you know that your website *does not appear to load
in any browser* on Android devices (tablets, phones). I've tested
Chrome, Firefox, and Opera Mini, on two android devices, and in each
case, the browser ends up getting redirected to a "server not found"
page, apparently due to a series of redirects configured on your web
servers.

I've included a bit more detail on a page in our bug-tracker here:
  https://bugzilla.mozilla.org/show_bug.cgi?id=873616
(Note that this isn't to suggest that it's a bug in Mozilla; our bug
tracker is just a convenient place to investigate this).

I'm hopeful that someone on your team can dig in and fix the problem, so
that users will be able to visit your website on their Android devices.
 Please let me know if I can be of any assistance (or feel free to post
on the bugzilla page that I linked above).

Thanks!

This works correctly now. I'm now redirected to:
 http://m.hyatt.com/mt/taipei.grand.hyatt.com/en/hotel/home.html
instead of the 404 page from comment 0.
