Issue with reverse-proxy

Thank you for more wide explanation of this issue. With all respect I think that I have already knew about this issue like it is. After I have done some number of Apache settings for PhP application I still have some deficit (probably) in Apache to Tomcat settings. Problem persisted in setting the Apache to Tomcat for sub-wiki as it itself where decent ambiguity is present as here as on the internet (in other forums). Everybody has been able to set it to parent wiki not to subwiki. Although I am immensely grateful for your time invested to me, but I still have to do testing and research for this issue. I think we just didn’t understood each other I need to set domain to subwiki where the domain has none text same with name of xwiki. It is more like: 123.asdf.com = 123.asdf.com/xwiki/wiki/jkljkl where “jkljkl” is name of subwiki. Do your settings actually work for particular subwiki? Or is it just working settings for Apache to Tomcat connections? I am deeply sorry, but this settings besides the “DocumentRoot” which you said is irrelevant does not wear any signs of particular subwiki aim, everything then is just set to /xwiki not /xwiki/wiki/jkljkl (example).

As I said, I am very grateful and I feel sorry for not solving this situation. I will try my best in upcoming days to solve this issue. I still think and there might be some kind of misunderstanding. I thank you for every advice you have gave to me so far.
Have a nice day.
