ReverseProxy for UserDir

[Ninad <ninad@xxxxxxxxxx>]

Dear All,

My self Ninad. I am novice user of apache httpd and linux.

I  have an intranet web server (internal.com) with UserDir configured on it. I am able to access it with following urls without any issue from my LAN network.

http://internal.com/~a
http://internal.com/~x.y
http://internal.com/~p_q

Here "a", "x.y", and "p_q" are users on internal.com server.

Now there is another httpd server which is connected to the internet  (external.com) and I want to reverse proxy only for userDir hosted on  my intranet server (internal.com). I tried following configuration but it did not work.

ProxyPreserveHost On
ProxyPass /~ http://internal.com/~
ProxyPassReverse /~ http://internal.com/~

I am getting following errors in error_log if I use url like "http://external.com/~a" or "http://external.com/~x.y" from internet.

AH00128: File does not exist: /var/www/html/~a
AH00128: File does not exist: /var/www/html/~x.y

I kindly request you to guide me in this regard.

Thank you very much in advance.

Regards,
Ninad.
