    Strict check

    Asked by slimflimzy on August 20, 2012 at 04:33 PM

    What does "Strict Check" under advanced settings/unique submission do?
    I thought it wasn't possible to limit submissions anymore?

    How does it work?

    Hi slimflimzy and thanks for contacting us.

     

    Sometimes you may want to prevent users to make submissions on the same form.
    Unique submissions is for that purpose. You can access unique submissions by:

    On the Form Builder:

    1. Open "Setup & Embed" tab on toolbar,


    2. Click on "Preferences"

    3. Go to "Advance Settings"
    4. Change the unique submissions level you like.

    5. Close and Save your Form.



    There is a difference between strict and loose check.

    Loose check controls the cookie.
    Strict check also controls the IP address.

    If you set strict check people in the same network (in the same school, college,university, institution ) will not be able to make form submissions as the IP address in the same network is the same. If you are considering the target audience as students in the same school you should set loose check.

     

    Please let us know if you need further assistance.

    Alessandro

    Just to be clear: does "strick check" work with cookie and IP address or only IP?

    Which of the two would be better suited to curb attackers from sending limitless replies in an attempt to crash me?

    Will either of these stop users whose IP address changes dynamically over a short time period?

    Strict check does work with both, lose check only work with cookies . Both have advantages and disadvantages. for example if you set a strict check and your audience is a college, you might prevent people within the same IP network to use your form . However in the case of a dynamic IP address, the strict check might be useful because it will still work with cookies.
