"Request denied by pfSense proxy: 403 Forbidden" mesaji saniyorum sizin Redirect mode taki bir web sayfasina yonlendirip,kullanicinin o sayfaya ulasamamasindan ileri geliyor.Bunun yerine asagidaki ayari yapmak cok daha basit olacaktir.

TargetCatagories altinda;
Redirect mode:int error page secilir
Redirect :kullanicinin gormesini istediginiz hata mesaji yazilir.

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
#                _- client user
#                ~~- client group
#                [t] - target group
#                - client url

Example:

#        sgerror.php?url=401 Unauthorized access to URL 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
