apache2 - apache 2 proxypassreverse appends virtualhost port -


i have been trying setup reverse proxy using apache 2 mod_proxy , proxypass & proxypassreverse directives.

i installing wso2 identity server , wish access app using url such following . 

hxxp://myserver.domain.com/wso2/

the myserver.domain.com accessible on internet

internally on network have set virtualhost running in apache2 configuration following parameters:

for various reasons, port 80 unavailable , virtualhost must stay :8080.

finally, here virtual host configuration

<virtualhost *:8080>    <location /wso2/>     proxypass hxxps://internal.wso2.node:9443/     proxypassreverse hxxs://internal.wso2.node:9443/   </location>   proxyvia on  proxypreservehost off  proxyaddheaders off  proxyrequests off  sslproxyengine on  sslproxycheckpeercn off   </virtualhost>

the issue:

i can use web browser ( firefox/chrome) request http://myserver.domain.com/wso2/ resource. in log files see request hit apache server , virtualhost catches /wso2/ location.

it passes through proxy , lands on internal.wso2.node server. however, product wso2 preforms several redirects which, in log files see requesting resource port appended.

here request flow

  hxxp://myserver.domain.com/wso2/  -> hxxps://internal.wso2.node:9443/   redirect x3   hxxps://internal.wso2.node:8080/carbon ->    hxxps://internal.wso2.node:8080/carbon/admin/login.jsp    web browser   hxxp://myserver.domain.com:8080/wso2/carbon/admin/login.jsp

for reason apache response appends virtual host url requesting.

if remove port:8080 , request again full url access resource fine. attempt access using http://myserver.domain.com/wso2/ result in redirects , port appended.

as per covener's suggestion culprit in case proved following directives:

usecanonicalname off usecanonicalphysicalport off

additionally, web app trying access makes use of sessions , cookies, therefore must proxy those, see added directives under proxypass & proxypassreverse.

therefore updated virtualhost configuration file should this

<virtualhost *:8080>     servername: myserver.domain.com    usecanonicalname off    usecanonicalphysicalport off    <location /wso2/>     proxypass hxxps://internal.wso2.node:9443/     proxypassreverse hxxs://internal.wso2.node:9443/     proxypassreversecookiepath / /wso2/     proxypassreversecookiedomain internal.wso2.node myserver.domain.com   </location>  proxyvia on proxypreservehost off proxyaddheaders off proxyrequests off sslproxyengine on sslproxycheckpeercn off  </virtualhost>
