NGINX using $server_port in upstream -


i want proxy_pass upstream has 1 host multiple ports. have:

upstream myups {   zone myups 32k;   server myups.hostname.com:$server_port; }

when try configuration , reload nginx, following:

"invalid port in upstream"

the basic idea simple, want keep port passed in server (server_port), , use when pass on upstream. can hard code port numbers in upstream this:

... server myups.hostname.com:1234; ...

and work every time specific port. need able use multiple ports.

edit - proxy_pass looks like:

proxy_pass http://myups; -or- proxy_pass http://myups:$server_port;

i not know if second 1 right, playing see if possible pass port number location upstream.

other things ive tried didnt work:

setting parameter in map acting global variable. specifying port "location" section of server. set hash (only works ip doesnt here.).

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
