environment-variables - Apache check if user is browsing their home directory

Question

I for example I've got webserver's root directory /var/www/. And user's home directory: /var/www/testuser/. I also have basic authorization setted up, so there is a user with username testuser which successfully authorized. How can I check if the testuser is browsing their home directory by the means of webserver alone? This is how far I've got:

# Getting "testuser" out of "/testuser/echo.php"
SetEnvIf Request_URI ^/(.*)/ URI_HOME=$1

# Getting base64 encoded part out of Authorization header
SetEnvIf Authorization "^Basic (.*)$" X_HTTP_AUTHORIZATION=$1

# Converting base64 part to plain text, extracting username and comparing it with home directory 
SetEnvIfExpr "tolower(unbase64(%{ENV:X_HTTP_AUTHORIZATION})) == %{ENV:URI_HOME}" USER_IS_IN_HOME_DIR

The major problem is that Apache doesn't have REMOTE_USER setted up on the stage when SetEnvIf is working. So I absolutely have to parse Authorization header from request. I almost done it, but I have to cut out part after column to make comparison proper.

How can I do it?

以下似乎工作：

SetEnvIf Request_URI ^/(.*)/ URI_HOME=$1

SetEnvIf Authorization "^Basic (.*)$" X_HTTP_AUTHORIZATION=$1

SetEnvIfExpr "unbase64(%{ENV:X_HTTP_AUTHORIZATION}) -strcmatch '%{ENV:URI_HOME}:*'" USER_IS_IN_HOME_DIR

任何想法如何改进它？
