Well, I'm not sure there is an HTTP header which would tell me the OS nor
processor type of the machine hosting a visiting browser unless this is
included in the user agent string. Go here with any browser to see what
it is telling the world about itself in its User Agent HTTP header:
http://timil.com/temp/browser.php?version=latest
NetSurf 3.7 #3798 says "NetSurf/3.7 (RISC OS)". 

Hopefully, a browser doesn't tell lies in that string or if a user
changes it then obviously it won't be detected OR checks for OS versions
and whatnot can be completely spurious and unreliable anyway. You almost
need Google Translate anyway to know that "...Windows NT 6.1; WOW64..."
is actually Windows7-64.

As I explained, the Calendar page detects the browser name in the
HTTP_USER_AGENT string.
The chunk of the page which does that and generates the welcome message
is here http://timil.com/riscos/calendar/netsurf?version=latest

The purpose of it is to do this:
Find out which Browser is visiting.
If it is NetSurf, Otter or Firefox print a personalised welcome message
then:
  Is JavaScript active?
   - yes: print one message in RED (using JavaScript)
   - no: print in black, another message; If NetSurf, print some more.

As you have a problem with both machines it could indicate that your
network connection could be caching files somewhere incorrectly. Using a
dummy variable appended to a URL will/should force a fresh copy of that
file to be used and not a cached one:
http://timil.com/riscos/calendar/?version=latest

The user could be consistent in not changing the option in both browsers
correctly (!) or your copies of NetSurf (or your hardware) are corrupt
and should be replaced. It seems unlikely that both machines would have
the same problem unless you are running the exact same copy of NetSurf
via Share (as I do). But doing the same wrong thing on both machines
would be possible! After all, someone else with the same version and
hardware as you does not experience the same problem.

Well, back to the page being displayed (wrongly) in your NetSurfs, and
after ensuring that "Disable JavaScript" is ticked in the Content
Choices, what happens when you click on "Set" with Select? 
If the Content Choices dialogue closes, is the Disable JavaScript option
still ticked if you then re-open it?

Another thing you could try is deleting whatever cache you have for
NetSurf. Use the Utility !ShowScrap (or into a command window type 
Filer_OpenDir 
and then press ). Delete the contents of WWW.NetSurf.Cache

There there could instead be a software clash so try and remove anything
non-standard. Have you added things such as MouseAxess to both machines?
I deleted that years ago following a tip and lots of supposedly unrelated
weirdness stopped happening

. We just need to find out what's causing yours.

I'm puzzled because I'm getting the same behaviour on both ARMX6 and 
RiscPC, as I would expect using the same version of NetSurf. Does it 
contain any alternative paths depending on OS version or processor 
type?

Granted, but you need to know in advance that you'll need to Adjust- 
click on any link off the calendar. Of course the root cause is that 
NetSurf doesn't save updates to iframes it its history.

I've only seen messages like that with Phoenix. ;-)

Also odd, because when I select the HTML-only link it doesn't seem to
redirect at all.

Correct. It didn't did it? With NetSurf's semi-JavaScript enabled you saw
a white page with only "RISC OS Event Calendar" written in it.

Yes, so what you do is click on the HTML-only version.

Why do people find this complicated?

I have no means to change the message Google Calendar puts in the iframe
but if you think it through, it makes complete sense and you have to
click on the HTML-only version because the browser you are using is, um,
incomplete.

Or perhaps you are being deliberately obtuse, I'm not sure.

Beacause it's offering you the non-JavaScript alternative. You need to
select it. Oh, what a hardship.

I had js off when I first visited the page, but received what must 
have been the js version, with just a blank white box in the middle of 
the page. So I then tried with js on, still got the exact same page.

However having just turned my ARMini back on and tried again, I now 
get the version that says "Welcome NetSurf user, you have JS 
disabled". So something must have been wrong with the page caching.

However, the calendar still doesn't display. Now I briefly get a "Bad 
redirect URL" error in NetSurf's status bar :-(

NetSurf v3.6 (19th Nov 2016) - the release version.

Others have it working so there must be something going on here. I'll 
have more of a play over the weekend.

Thanks,
Bryan.

It's contradictory. When you open the page it says "Your Javascript 
ios disabled as it should be" at the top, then underneath Google 
calendar says "Your browser does not appear to support JavaScript but 
this page needs to use JavaScript to display correctly. ...". However

I've just tried it on my ARMX6 (OS 5.23) and it works just the same.

I have JavaScript enabled here as a matter of course (Choices-->
Content--> Not ticked, which appears to be the default setting. The
calendar display is incomplete with the message "You may need to disable
Javascript and reload this page" If I then disable JS and reload the page
the display area has a message "Your browser does not appear to support

How? I can only report what I see! I call up the site, it tells me 
that JavaScript is on, I turn it off, and the site still tells me that 
it's still on. How could I have made an error that made that happen?

Is it something to do with the ARMX6, or with something else that I'm

I only asked :-)

Must be a problem with that version. The message saying it is ON is

You shouldn't need to quit, only reload after SETting that Content Choice
