Upsteam + proxy_redirect?

Server NGINX
1

Hi,
here is part of nginx.conf ; in some condition 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 and users can see the real site behind
the mynginxserver.com

can i use proxy_redirect when i use upstream ??

users type myngixxserver.com in their browser;
images stores on 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;
}

upstream myimages {
server image.mysite1.com;
}
location /v1 {
proxy_pass http://www.mysite1.com;
proxy_redirect http://www.mysite1.com/v1
NameBright - Coming Soon
}

location /v2 {
proxy_pass http://mysites/v2;
proxy_redirect http://www.mysite1.com
NameBright - Coming Soon;
}

location /images {
proxy_pass http://www.mysite2.com/images;
}

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
