-- The table is created using shell environment variables leaving out only 'DOCUMENT\_ROOT',
|
|
-- 'SCRIPT\_PATH' and the regular shell variables (e.g., IFS, HOME and PS1).

-- See [information on CGI environment variables](http://techpubs.sgi.com/library/dynaweb_docs/0530/SGI_Developer/books/NetscapeSrv_PG/sgi_html/ch01.html).

|
-- Fields present in the 'real' env table but not in this one are: 'HTTP\_VERSION'
|
|
-- and another table 'headers' which is mostly mirrored by the 'HTTP\_*' fields.
|
|
-- Note that the 'headers' table may contain extra fields (e.g., 'cache-control').
