Hi,  
here is part of nginx.conf ; in some condition [mysite1.com](http://mysite1.com) redirect  
users  
to some of its url so i need to use proxy\_redirect in my locations;

now i want to start using upstream to add load balancing to my site;

the location v1 is working fine with my main site but when i want to  
change its setting to something like location v2 it does not work and  
redirect browser to [mysite1.com](http://mysite1.com) and users can see the real site behind  
the [mynginxserver.com](http://mynginxserver.com)

can i use proxy\_redirect when i use upstream ??

users type [myngixxserver.com](http://myngixxserver.com) in their browser;  
images stores on [mysite2.com](http://mysite2.com);  
i will add more server to my upstream when the problem solves;  
sorry for my bad english  
mystic and mysite2 ip addresses are invalid

if more info is needed plaza tel me  
thank you in advance;

upstream mysites {  
server [www.mysite1.com](http://www.mysite1.com);  
}

upstream myimages {  
server [image.mysite1.com](http://image.mysite1.com);  
}  
location /v1 {  
proxy\_pass [http://www.mysite1.com](http://www.mysite1.com);  
proxy\_redirect [http://www.mysite1.com/v1](http://www.mysite1.com/v1)  
[NameBright - Coming Soon](http://www.mynginxserver.com/v1)  
}

location /v2 {  
proxy\_pass [http://mysites/v2](http://mysites/v2);  
proxy\_redirect [http://www.mysite1.com](http://www.mysite1.com)  
[NameBright - Coming Soon](http://www.mynginxserver.com/v2);

Try looking what your backend actually returns in ‘Location’  
header.

The difference is upstream name: in v1 you use your domain (the  
same as in proxy\_redirect), while in v2 you use upstream{} block  
name. Upstream name is used in Host header in request to upstream  
by default[1], and this may (and likely will) cause your backend  
to return different redirects.

BTW, proxy\_redirect default will use upstream name as well, and  
this should handle such situations transparently. See [2] for  
details.

hi again  
only one question left;  
i want to add more server to my upstream;  
i tried to use this :  
proxy\_set\_header Host $upstream\_addr;

but $upstream\_addr contains port of upstream server too;  
i did not find any thing yet to remove port from $upstream\_addr;  
how can i do it ?

thanks again
