Partial rendering requires a browser that supports W3C DOM Level 1.0

It's actually easier to ask youwhat browser you want supported? I can tell you that it works on IE 6 and 7 (and probably 5.5... writing off the top of my head).

I have also successfully used Partial rendering with FireFox (v1.5 and 2.0), Safari (2.04 or greater), and K-Meleon 1.02 (another win32 mozilla browser)... I have heard it works fine with both the latest Netscape and Opera.

If you are wanting to support something like IE 4 or <shudder /> Netscape 4 then you are definitely out of luck.. it ain't happening. Much of the reason for this is that W3C DOM spec has caused convergence in the browsers javascript models. Everything is close enough that you can write a library that makes all code cross browser (or at least close enough that the numbers of quirks is small).

Thanks for the reply.

Is there a definitive list of what browsers are supported? I reckon it could be crawlers that are having a problem too which could mean indexing pages is a problem?

Anyone know what code to put and where to switch off partial rendering if it's not supported?

Thanks.
