Re: WC:>: Hiding EMail Addresses in Web Pages (was: Commercial sites)

[Tony Anastasi http://web.hosting.au.com]

I think a better way is to leave your email in the cgi reply form, and not have the browser pass it to the cgi script..

if you can't code cgi's or your not allowed to use cgi's then mimeify it..

so that [EMAIL PROTECTED] becomes

youremail@yourhost.com

in your html page. your browser will uncode this and you'll see that it works..

so when you put it in a tag like mailto: the browsers will be able to decode it and the visitors will be able to send you emails..

should i write a cgi to code this for you guys?.. so you put your email address in the form, click a button and the script returns the above codes?..

this totally stops the current batch of spamming spiders.. i've had it on my geocities test page for 8 months, and i havent gotta a single spam.. there are three emails on that page. and the uncoded email address gets about 1-5 spams a day from that page on geocities.

so i know it is still working as a good anti-spamming tool.
