reverse proxy http to tomcat

Question

I've configured an Apache server with SSL and reverse proxy to a tomcat

<VirtualHost domain.com:1443> [...] ProxyRequests Off ProxyPreserveHost On ProxyPass / http://local.com:8080/ ProxyPassReverse / http://local.com:8080 SSLEngine on [...] </VirtualHost> 

Tomcat is listening on 8080. The issue is that the app on tomcat is redirecting the request (HTTP 302 Moved temporairly). For example, if I use the URL https:// domain.com:1443/folder, reverse proxy launch the request http:// local.com:8080/folder, then, the app redirect to "/subfolder", so the final request is: http://domain.com:1443/folder/subfolder. Result is a 400 Bad request error code, as the request is HTTP on my SSL port.

Do you know how I can fix this issue ?

Thanks in advance.

Instead of plain http proxy, use proxy_ajp. Adapt the example below to match your needs, i.e. it is up to you to proxy everything to the container or only a namespace:

ProxyRequests off ProxyPassMatch ^/(your_app)(.*) ajp://localhost:8009/$1$2 ttl=120 ping=1 

Ensure that server.xml in your tomcat configuration includes an AJP listener. The executor is optional.

<Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="150" minSpareThreads="4"/> <Connector executor="tomcatThreadPool" port="8009" protocol="AJP/1.3" connectionTimeout="20000" URIEncoding="UTF-8" redirectPort="8443" />
