How hard is it to code a proxy? I can design it in photoshop but i have limited knowledge of html/css.
I don't know about coding, but you could buy a coded proxy theme with full rights from the templates section in DP and just use its codes.
is about php / curl / asp / cgi or what the script use , not about design in .html, design can be done later if you talk about making a proxy not a template
You could download a free proxy and then install one of their pre-made templates that fits the design your looking for. It won't be as custom as you'd probably like it, but it will save you a lot of time and hassle.
You mean coding the design or coding a script, that proxyfies pages? if You only talking about coding its design, then You should be able to undesratnd the basics in less than 10 hours. If You're talking about writing Your own script - well, it is a lot thougher and without knowing a lot of php/cgi knowledge it is nearly impossible. Good proxy needs from You to undestrand multisessions, cookies and some other stuff, that must be done with user knowledge to provide him the service
