Apache + MOD_JK: Rewriting URLs + ProxyPassing thorugh AJP

Question

I've a frontal server with Apache 2.4.23 deployed + OpenSSL 1.0.2j.

Then I've another server with Tomcat 7 installed.

The idea is that Apache has a VHOST on *:443, which uses ProxyPass to send the request via AJP to Tomcat server according to specifyc URLs.

That's my vhosts.conf file (it has SSL configuration as I don't want to use the httpd-ssl.conf file, cause I've to change many things on it), according to this site:

https://mozilla.github.io/server-side-tls/ssl-config-generator/

</VirtualHost>

Now as you can see, I've 2 proxypasses according to how URL is. That's because I've and "admin"/backend zone, and a user zone. First proxypass is per Admin Zone, and second one to User zone.

Now, for those sites I need those URLS:

ADMIN: https://xin.foo.com/bar/bar

USER: https://xin.foo.com/bar/bar?app=personal

I'm using Apache server on a "local" context right now, which means I have not a TLD subdomain already with the Apache server public IP on it. So, on my local machine in the office, I've edited my "hosts" file on "windows/system32/drivers/etc" and added the line:

xin.foo.com Y.Y.Y.Y (which is the IP address of the Apache frontal server). This way I can emulate from my machine, what a public acces from inet will be.

Said all that, now comes the thing:

Inet people, will access thorugh https://xin.foo.com. That's it.

I want "https://xin.foo.com" to access directly to USER zone.

And something like https://xin.foo.com/admin, to access to ADMIN backend zone.

Then, here I guess are 2 things to take in account:

AJP proxypasses
Possibility of mod-rewrite'ing first with parametters or something, to force the already configured proxypasses to work? As tha aplication mounted on Tomcat server, expects some parameters (?app=personal) to show user zone. And no params = admin zone.

Maybe I've to delete the Proxypasses and do some mod_proxy_ajp to it?

What will be the right way to do it and how? I would appreciate the final recipe, as mod_rewrite and Porxypass is not my speciality... And I'm convinced that even those 2 proxypasses are wrong, but that's what they got me.

EDIT ACCORDING TO COMMENTS:

To sumarize, all is working porperly right now, but I need to write the URLs as explained before, to acces the proper zones. What I want is to change the behaviour of the server, according to what is logic, and let the simple TLD url go to user zone, and "/admin" to backend zone. I've added a rewirte from http to https which works OK. Now I've thought that I can add a rewrite which says:

"IF https://xin.foo.com THEN https://xin.foo.com/bar/bar?app=personal"

and

"IF https://xin.foo.com/admin THEN https://xin.foo.com/bar/bar"

With that, I guess the AJP proypasses should still working normally. And what would be of an A+ grade, would be to not to modify the URL on the browser, so people keep reading "https://xin.foo.com" for the real and "hidden" "https://xin.foo.com/bar/bar?app=personal".

Thanks you all so much, and kind regards.
