-# SquidGuard error page generator
-# (C)2006-2007 Serg Dvoriancev
-# ----------------------------------------------------------------------------------------------------------------------
-# This programm processed redirection to specified URL or generated error page for standart HTTP error code.
-# Redirection supported http and https protocols.
-# ----------------------------------------------------------------------------------------------------------------------
-# Format:
-# sgerror.php?url=[http://myurl]or[https://myurl]or[error_code[space_code]output-message][incoming SquidGuard variables]
-# Incoming SquidGuard variables:
-# a=client_address
-# n=client_name
-# i=client_user
-# s=client_group
-# t=target_group
-# u=client_url
-# Example:
-# sgerror.php?url=http://myurl.com&a=..&n=..&i=..&s=..&t=..&u=..
-# sgerror.php?url=https://myurl.com&a=..&n=..&i=..&s=..&t=..&u=..
-# sgerror.php?url=404%20output-message&a=..&n=..&i=..&s=..&t=..&u=..
-# ----------------------------------------------------------------------------------------------------------------------
-# Tags:
-# myurl and output messages can include Tags
-# [a] - client address
-# [n] - client name
-# [i] - client user
-# [s] - client group
-# [t] - target group
-# [u] - client url
-# Example:
-# sgerror.php?url=401 Unauthorized access to URL [u] for client [n]
-# sgerror.php?url=http://my_error_page.php?cladr=%5Ba%5D&clname=%5Bn%5D // %5b=[ %d=]
-# ----------------------------------------------------------------------------------------------------------------------
-# Special Tags:
-# blank - get blank page
-# blank_img - get one-pixel transparent image (for replace banners and etc.)
-# Example:
-# sgerror.php?url=blank
-# sgerror.php?url=blank_img
