Nginx doesn't redirect www no m in Safari, iPhone, iPad

Detlef_R · July 3, 2015, 1:04pm

The problem is, the site is entered with www in url in a mobile device
with
parameters in the url, it is redirected from www.domain.com to
m.domain.com
but the parameters entered with www.domain.com/parameters when
redirected to
m.domain.com doesn’t receive the parameters from thr url origin in www.

In conclusion www.domain.com/parameters should redirect to
m.domain.com/parameters but is redirected to m.domain.com, the
parameters
are clean. Is there a way no to clean it ?

The www config is the following :

server {
listen 80;
server_name www.domain.com;
…

  #to detect if the device with www entered in domain is mobile
  if ($http_user_agent ~*

‘(iPhone|iPod|iPad|Android|BlackBerry|webOS|Windows Phone)’) {
rewrite ^ http://m.domain.com$uri;
}

}

The mobile configuration is
server {
listen 80;
server_name m.domain.com;

...

}

It works for me as-is. I add your “if” at server{} level, and I see:

curl -A iPad -i http://localhost/parameters?key=value

HTTP/1.1 302 Moved Temporarily
…
Location: http://m.domain.com/parameters?key=value

What response do you get for a similar curl command?

A few things here:

“!” is special to bash, so you have to shell-escape it for “curl” to see
it.

“#” is special in a url; it is not part of the normalised variable $uri.

Possibly using $request_uri instead of $uri in your configuration will
be appropriate? They are different variables with different values,
so there are probably some cases where using one will break things.

Since you are using it in a redirect, probably $request_uri is the
correct one to use regardless.

Hi there

I changed to

#to detect if the device with www entered in domain is mobile
if ($http_user_agent ~*
‘(iPhone|iPod|iPad|Android|BlackBerry|webOS|Windows
Phone)’) {
rewrite ^ http://m.domain.com$request_uri;
}

I executed the command :

$ curl -A iPad -i

And the result was :

-bash: !/pt/–item-view/pt/32081/Mix-J: event not found

This only append’s with Safari, there’s no problem with Chrome (Desktop,
Mobile) or Internet Explorer in Pc, could this be a browser problem and
not
an Nginx configuration problem ?

Thanks

For one request that gets the response you expect, what does access.log
say that the request and user-agent are?

For one request that does not get the response you expect, what does
access.log say that the request and user-agent are?

Perhaps that will hint at where the problem is.

Good day

There was a problem in testing in the terminal with the character “!”,
it
should be with "" after, like this :

$ curl -A iPad -i

And the result was :

HTTP/1.1 301 Moved Permanently
Server: nginx
Date: Mon, 06 Jul 2015 08:50:10 GMT
Content-Type: text/html
Content-Length: 178
Connection: keep-alive
Location: http://m.alpha.centroproduto.com/

301 Moved Permanently

nginx

And in this case i changed the nginx configuration to :

if ($http_user_agent ~*
‘(iPhone|iPod|iPad|Android|BlackBerry|webOS|Windows
Phone)’) {
rewrite ^/$ http://m.domain.com/$1 permanent;
}

Hi

I tested in a iPad and Safari the request and the nginx log reported a
401
error :

xxx.xxx.xxx.xxx - - [06/Jul/2015:13:42:24 +0000] “GET
/pt/api_cp/user_counts/ HTTP/1.1” 401 27 “http://m.domain.com/”
“Mozilla/5.0
(iPad; CPU OS 8_3 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko)
Version/8.0 Mobile/12F69 Safari/600.1.4”

But this i think is not an error associated with faulty url

And the Nginx didn’t recorded the access in the nginx access.log file

Things seem to be getting a lot more complicated than they need to.

That’s not the configuration you started with.

You indicated that with your starting configuration, some requests did
get the response that you wanted, and some did not.

I have been unable to reproduce the “did not” case; probably because I
do not fully understand what your expectations are.

Can you go back to your starting configuration, and do whatever it takes
to get the “ok” request/response, and then show the access_log entry
for that request?

(Or just find the old log file.)

The log line should show a GET going to the “www” server, with a
response
code of 302. Ideally, it will also show the user-agent involved.

Then can you show the log line corresponding to a “not ok”
request/response? It should also show a GET going to the “www” server,
with a response code of 302, if I have understood correctly what you
have reported.

Comparing the two log lines, particularly the request and the
user-agent,
may show why the “not ok” one responded as it did.

Why don’t you try with requests to real pages, not to a fragment?
“#” and everything after this character isn’t sent to the web server,
it’s
only used by the web client.
You really should read at least:

Some browsers will keep the fragment after the redirect, some others
will
drop it.

Posted at Nginx Forum:

ramsoft75 · July 7, 2015, 9:21am

You should protect the URL with single quotes, to avoid the
interpretation
of character ! by the shell:

curl -A iPad -i
‘Website Domain Names, Online Stores & Hosting - Domain.com’

But if you put the URL
Website Domain Names, Online Stores & Hosting - Domain.com in a browser (at
least in Firefox), the browser sends to the web server only the first
part
of that URL:

https://www.domain.com/

because the character # is a special one.

Surprisingly, curl sends the full URL to the webserver.

Greetings,

Oscar

Hello,

Francis D. asked you several times to check the access.log file (you
should not find the fragment part in there).
oscaretu and I told you browsers don’t send the fragment part of an URL.

The problem isn’t from nginx nor the browser: it’s a normal behavior.

Best Regards

ramsoft75 · July 7, 2015, 11:29am

Hi there all and thank’s for the help

Dear oscaretu, the curl was tested with " doesn’t help, because ! is a
special character it needs a escaope after "", so the correct curl
command
for the terminal is :

$ curl -A iPad -i Website Domain Names, Online Stores & Hosting - Domain.com

Dear Francis D.

For the initial configuration :

if ($http_user_agent ~*
‘(iPhone|iPod|iPad|Android|BlackBerry|webOS|Windows
Phone)’) {
rewrite ^ http://m.domain.com/$request_uri;
}

For the example above the output in terminal is :

HTTP/1.1 302 Moved Temporarily
Server: nginx
Date: Tue, 07 Jul 2015 09:19:47 GMT
Content-Type: text/html
Content-Length: 154
Connection: keep-alive
Location: http://m.domain.com//

302 Found

nginx

It’s the same if i changed to :

if ($http_user_agent ~*

‘(iPhone|iPod|iPad|Android|BlackBerry|webOS|Windows Phone)’) {
rewrite ^/$ http://m.domain.com/$request_uri;
}

The problem is not from Nginx but from Safari witch doesn’t send the url
after #, the Safari removes the fragment.

There are some documentation about this in :

http://news.qooxdoo.org/http-redirects-and-loss-of-fragment-identifiers

The question know how to handle this # problem with Safari.

Thank’s for the help

ramsoft75 · July 7, 2015, 2:33pm

Yo don’t need to escape the “!” if you delimit the URL with single
quotes…

In deed there was no information in access.log, the only information i
published was from error.log with nginx debug mode and an error 302 is
not a
error. It’s not an Nginx problem it’s a Safari problem.
