Yes. Normally you have an index.php file which includes pmwiki.php (wherever  
pmwiki.php is, in the same directory or elsewhere) and use URL rewriting to  
redirect requests to index.php.

Here is a sample .htaccess which I use on many different sites:

  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-l
  RewriteRule ^([A-Z0-9\x80-\xFF].*)$       /index.php?n=$1  [QSA,L]

The RewriteCond lines limit the redirection only if the requested URL  
isn't an actual filename or directory.

The above .htaccess and index.php are in the DOCUMENT_ROOT directory of the  
server, and in the same directory are wiki.d/ and uploads/.

If your index.php file, wiki.d/ and uploads/ are in a subdirectory, for  
example pmwiki/index.php, and you want your URLs to be like


then you need to edit the .htaccess file in the root directory, not the one  
in the pmwiki/ subdirectory. Here is an example of such a working file:

  RewriteEngine On
  RewriteBase /
  RewriteRule ^$       /pmwiki/index.php [QSA,L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-l
  RewriteRule ^([A-Z0-9\x80-\xFF].*)$       /pmwiki/index.php?n=$1  [QSA,L]

The first RewriteRule line redirects www.shadlenlab.columbia.edu/ without  
anything else to PmWiki, the last redirects anything that is not a file/dir  
also to PmWiki.

The /pmwiki/index.php file includes pmwiki.php (wherever it may be) and sets  
the $ScriptUrl variable and if needed, the $PubDirUrl, the $FarmPubDirUrl  
and the $UploadsUrlFmt variables.

The first example works for me with HTTPS off, the second with HTTPS on,  
without doing anything in particular.

I don't see why, it is possible that some of the $_SERVER variables of the  
system are not correctly presented to PmWiki.
