在 htaccess 中显示结果

Question

Is there any way to display htaccess directives results in real time? For example:

RewriteCond %{DOCUMENT_ROOT}

Are there any instructions that can be placed inside htaccess to display %{DOCUMENT_ROOT} value?

I know that can be accomplished with a PHP script in the right address, but I was wondering if it's also possible inside htaccess?

Answer 1

Try this

RewriteEngine On
RewriteBase /
RewriteRule (.*) /$1?docroot=%{DOCUMENT_ROOT} [L,QSA]

Didn't have the possibility to test this but should work

From the Apache 2.2 documentation

In addition to plain text, the Substition string can include

• back-references ($N) to the RewriteRule pattern
• back-references (%N) to the last matched RewriteCond pattern
• server-variables as in rule condition test-strings (%{VARNAME})
• mapping-function calls (${mapname:key|default})
