Web proxy for smartphone?

Hello

I'd like to call some web sites through a proxy to rewrite web pages on the fly.

Since 1) Privoxy isn't supported/maintained for Android and 2) there doesn't seem to be a way to configure Android to use a web proxy without rooting the phone, I was thinking of doing this:

Smartphone web browser -> PHP script on server to get URL to call -> Privoxy -> filtered page -> PHP script -> smartphone

IOW, when I wish to view a filtered site on my smartphone, I'll call the PHP script running on my home PC, which will itself outsource this to Privoxy, which will filter the page, to be sent back to the browser.

Does this sound good, or is there a better way?

Thank you.
