    Ben  burdaki  Request denied by pfSense proxy: 403 Forbidden  yazısını editlemek istiyorum. Forumda  bulamadım bunla ilgili bir yazı.

    Yardımcı olabilirmisiniz…



  • "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
