Nginx Reverse Proxy Lowercase URL and some exceptions to the URL

[Alex Med]

I have the following server configuration.  I have two problems that I would
appreciate if someone can tell me what I am doing wrong:

1- this location is not respected since the configuration lowercases all
uris without respecting these locations.  Please note that api,
contentAssets, categoryServlet are paths, not directories or folders.

location ~
^/(api|contentAsset|categoriesServlet|DotAjaxDirector|html|dwr|dA)/{}


2.  It seems that if I am in a reverse proxy I have to input the proxy
definition in every location because otherwise it does not work.  Is the a
more practical way to do this?


Thank you for all your help!

Lex

Note: I have changed the proxy IP address and port for x and Is.
