Hey all

I'm planning to allow public visitors to upload a plain text file (max 9kb, but usually it'll be around 5-6 kb) so that my script can read the uploaded file and then pre-populate a HTML form.

I know how to carry this out, but just wondering if this is considered safe? If I implement the proper $CGI::POST_MAX value so that it doens't allow anything 9kb or more to be uploaded, am I all set? I also know to check the meta type of the file being uploaded. Since I'm only allowing a plain text file, then I thought it'd be safe. I also know to make sure the uploaded text file has no execute permissions.

The only thing I'm really concerned about now is if someone will build a bot to SPAM it so it uploads a new file every 10 seconds. Is this something that I need to worry about or is this something my HOST will have to implement when configuring the web server? Last question I have is, is it wise to use a CAPTCHA system for this type of uploading feature?

Thanks
