Apache Proxy CORS on end server being down or timing out -


i using angularjs on ui , cant tell difference between server being down or timeout both respond following. due cors. when server down or request times out apache not add cors header.

"{"data":null,"status":0,"config":{"method":"get","transformrequest":[null],"transformresponse":[null],"url":"https://api.domain.com/containers/60539","headers":{"accept":"application/json, text/plain, */*"}},"statustext":""}"

how can make sure proper 502/503 statuses apache on request while having 200 on options?

thank you!

current config:

<virtualhost *:443>   servername api.domain.com   <ifmodule proxy_module>     proxyrequests off     sslproxyengine on     sslproxyverify none      sslproxycheckpeercn off     sslproxycheckpeername off     proxypass / 1.1.1.1     header set access-control-allow-origin "*"     header set cache-control "max-age=0, no-cache, no-store, must-revalidate"     header set pragma "no-cache"     header set expires "wed, 11 jan 1984 05:00:00 gmt"   </ifmodule>   sslengine on   sslcertificatefile "${wildcardsslcrt}"   sslcertificatekeyfile "${wildcardsslkey}"   sslcertificatechainfile "${wildcardsslchain}" </virtualhost>

instead of header set use header set:

header set access-control-allow-origin "*"

https://httpd.apache.org/docs/current/mod/mod_headers.html#header explains:

the table corresponds always used locally generated error responses successful responses.

and couple of guides guidance:
