Re: math variable security [MEDIUM LONG]
This WebDNA talk-list message is from 2000
It keeps the original formatting.
numero = 33497
interpreted = N
texte = Sorry I don't have an ego so it cannot seem like you are picking on me. I just like to fix my problems, work logically and build on what I already have.So regardless of wether you see it as lazy or not I don't care, it was a function of webcat in version 3 and it has been stripped out for no real reason, other than your supposed security flaw. Regardless of the fact that I did not use it in critical situations. In fact I claim to be a lazy programmer. If I can find a better, shorter, way to code then I will use it. The code I posted was an example I hacked up to illustrate the point that there was NO security hole in this. Of course we can pick the code over, or look at it as a whole. Is there a security hole? Is there a reason to plug a non-existent(My interpretation) security hole and make previously written code unusable.Here is the code written to compensate for johns corrections and provide a small amount of comment for arguing logic not the specifics of the code.[!]Text Variables set so that other pages can post this information or that cookies can pull this information and override or reset the variables.
