Tableau Reverse Proxy Issue - apache

Question

I want to make Tableau (which is on an internal network) accessible on the public network. One of the ways recommended by Tableau Support is a Reverse Proxy.
I have set up the required modules and have the reverse proxy functioning. The login page is available through these settings in httpd given below. However, once I log in and want to open Projects, Views etc. It routes to
http://actualsite.com/#/vieworproject
which should actually be http://actualsite.com/tableauaccess/#/vieworproject.
Here is the httpd configuration:
ProxyPass /tableauaccess/ http://tableauserverexample.com/
ProxyPassReverse /tableauaccess/ http://tableauserverexample.com/
<Location /tableauaccess/>
Order deny,allow
Allow from all
ProxyHTMLURLMap / /tableauaccess/
</Location>
This doesnt solve the main issue with #. I tried
ProxyPass /#/ http://tableauserverexample.com/#/
ProxyPassReverse /#/ http://tableauserverexample.com/#
But it doesnt help. Any suggestions?? Thanks!

We had this same issue recently. Your httpd.conf file is technically correct for mod_proxy, however the url you are attempting to use is not supported by Tableau. You cannot use:
http://actualsite.com/tableauaccess
But rather you must use the format:
http://tableauaccess.actualsite.com
We ended up setting up that sub-domain name and then using a VirtualHost block such as:
Listen 80
NameVirtualHost *:80
<VirtualHost *:80>
ServerName actualsite.com
DocumentRoot "/path/path2/pathx"
</VirtualHost>
<VirtualHost *:80>
ServerName tableauaccess.actualsite.com
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://tableauaccess.actualsite.com/
ProxyPassReverse / http://tableauaccess.actualsite.com/
<IfModule mod_cache.c>
CacheDisable *
</IfModule>
RequestHeader set X-Forwarded-Proto "http" #or "https", depending on preference
</VirtualHost>
Be sure to double-check your Tableau server to update the URL format.
