+# 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
