Subject: continue clarification of RewriteBase, lots of users who install little
X-Git-Tag: 2.3.4~17

continue clarification of RewriteBase, lots of users who install little
PHP apps with an Alias a) leave off RewriteBase then b) add the filesystem
path instead of the URL-path then c) spend hours trying to debug
the RewriteRules themselves.
