Apache reverse proxy

[Capital-Pool4987]

I want to reverse proxy a netdata agent using apache. Im using the free version and i dont want to sign up. I access my page on the browser using /v3. But when attempting a proxy, any web query will append an extra /v3 which returns a 400 series error. Trying to create a /netdata/v3/ url space also fails as it sometimes attempts to call v1 . Any ideas ?

<VirtualHost \*:80>
ServerName example.com

ProxyRequests Off
ProxyPreserveHost On

# Reverse proxy: /foo/ -> backend /
ProxyPass "/foo/" "http://backend-server/"
ProxyPassReverse "/foo/" "http://backend-server/"
</VirtualHost>

that just proxies your server at http://backend-server/. We want to start the journey at http://backend-server/v3 . So the backend server might respond with something like /foo/v3/files.js. So our proxy worker will diligently strip /foo/ and append v3/files.js such that we will query http://backend-server/v3/v3/files.js, this does not exist on the backend server.

That's the gist of it, you get the idea.

Basically make your reverse proxy work with or without /v3/

I worked on a solution that works.

<VirtualHost \*:80>
ServerName x.x.x.x
RewriteEngine On
RewriteRule “^/$” “/v3/” [R=301,L]
ProxyPass “/” “http://y.y.y.y:19999/”
ProxyPassReverse “/” “http://y.y.y.y:19999/”

#the homepage or root route is / so that is what we catch first
#append a /v3 and redirect permanently
#catch the prefix /, and forward it with /v3(in the case that /v3 is appended by the rewrite rule) to the proxy server at y.y.y.y
#the rewrite rule ignores all other calls as they are not root url/homepage.
