+SSL is supported and can for example be used with Letsencrypt certificates, you just need to convert them to a Java key-store. See this [bash script](https://github.com/SEPIA-Framework/sepia-installation-and-setup/blob/master/sepia-custom-bundle-folder/letsencrypt/copy-cert-to-keystore.sh) for an example.

+Before using: Be sure to check-out the source to tweak the number of possible threads for more performance. If you use the IP filter for local addresses make sure that there is NO OTHER proxy in front otherwhise all your IPs will be local and the filter will NOT WORK!  
 
 Good to know: Thanks to Undertow it also works as proxy for WebSocket servers out-of-the-box :-)
 
-### To-do
-Introduce a config-file and maybe some command-line options to handle custom path-to-target mappings.
