    I've been seing some asp script on my log file every time before a submission of a link is completed.

    So this is auto fill form I would say....
    SEMrush
    How can I add a enter this code to make sure it isn't an auto complete.

    What do I need to do this?

    Hmmm,

    Im not quite sure I understand, but I think what your trying to ask is how to set up one of those `type what you see in the image` deals to keep automated submission programs at bay.

    The best way to do this would be through a server side script (as a client side solution could be analyzed by automated submission processes)

    The `image verification` setup has two components. The first is on the actual submission form, and consists of a routine which picks a random sequence of letters, than either generates an image or pieces together images from a library to reflect said random letters. This part of the script must also pass on this letter sequence to the second part, either by creating a new session and storing it as a session variable, or encrypting it and passing it as a hidden item in the form.

    The second component is the script which the submission form is `submitted` to. This form basically just checks the letter sequence the user entered against the letter sequence that was randomly generated in part one.

    Regards,
