Documentation of non-standard CGI environment variables
|
|
While documenting the CGI environment variables for the Apache Pocket
Reference I came across some minor discrepencies between the Apache
source code, documentation and the CGI specification.
It appears that the variable REQUEST_URI is unconditionally set. This
are not included in the CGI spec and not mentioned in the
documentation. REQUEST_URI is mentioned in the mod_rewrite docs, but it
appears even if RewriteEngine is set to OFF. DOCUMENT_ROOT and
SERVER_ADMIN are set and comments in the code say that these are Apache
additions, but that is not reflected in the documentation.
SCRIPT_URI and SCRIPT_URL are set if RewriteEngine is set to ON. This
is mentioned in the mod_rewrite documentation, but probably ought to be
mentioned in the mod_cgi docs and in howto/cgi.html
Does anyone have any comments on these variables? Once the book is out
of the way I'll work up a patch for the relevant documentation files.
