hi

i am currently experiencing some strange behavior if a user requests  
our domain with a . in the end of the domain. the actual problem is  
that our php code can’t really get along with that . in the end of the  
domain. so i tried creating an nginx rule that fixes this by doing a  
redirect to the correct domain. i tried multiple things, first i just  
left our actual production vhost untouched and added an additional one  
with the same server\_name but with a . in the end of the domain, like  
this:

server {  
server\_name mydomain;  
…  
}

server {  
server\_name mydomain.;

rewrite . http://mydomain$request\_uri permanent;  
}

but i found out that the requests never reach the vhost mydomain., i  
also tried to switch the order of those two, but all requests always  
go to the vhost mydomain without .

then another thing i tried was to catch the bad request based on the  
$host variable like this:

server {  
if ($host ~ “^mydomain.$”)  
{  
rewrite . http://mydomain$request\_uri permanent;  
}  
}

but now when i check the rewrite log i see that this $host variable  
doesn’t contain the . even if the request did. this means i request  
[http://mydomain](http://mydomain). in my browser and in the rewrite log i see:

2009/10/01 12:23:55 [notice] 8238#0: \*3 “^mytdomain.$” does not match  
“mydomain”, client: 192.168.56.1, server: mydomain, request: “GET /  
HTTP/1.1”, host: “mydomain.”

i am sure that the browser does not parse this . out, because the php  
can see it. and in the end of the above log line you can also see  
host: “mydomain.”.

does anybody maybe have an idea what else i could do to make sure that  
[http://mydomain](http://mydomain). gets redirected to [http://mydomain](http://mydomain)?

thanks a lot for help

Yes, server\_name ignores trailing dot. The dot is removed from $host  
too.  
Therefore you should unchanged $http\_host:

server {

- if ($host ~ “^mydomain.$”)

- if ($http\_host = mydomain.)  
{

- 

```
rewrite . http://mydomain$request_uri permanent;

```

- 

```
rewrite . http://mydomain$request_uri? permanent;

```

}  
}

Also if you use proxy for PHP, then you may edit “Host” header:  
proxy\_set\_header Host $host;

however, you can do the same with FastCGI.
