In the last couple of weeks we've started getting a weird support problem. A few people seem to be unable to save their profile or to save blogs. What happens is that they wait for 60 seconds or so and the browser then comes back with 400 Bad Request.

Now I haven't done anything likely to make this happen. And a 400 Bad Request should be pretty much impossible because it's the Server saying "I couldn't understand what the Browser told me." These are bog standard POST forms with nothing unusual about them. It's very hard to see how a browser could screw them up and send bad data back. And it's clearly only happening to a few people.

My gut feel is that this is either an IE6 update that's gone wrong. Or it's a browser add on such as Google Web Accelerator screwing up[1]. Or it's an ISP transparent proxy that is failing to pass data back correctly. I think it's IE6 only, but I'm not even sure of that. I haven't yet been able to find any common pattern to the people with the problem.

Any ideas? Because I've run out of them and I'm not sure what to look for next.

[1]Incidentally, Google Web Accelerator seems to be broken. It frequently returns a link to a RedHat Linux Apache initial installation screen rather than the target website. I have no idea where it's getting *that* from. [from: JB Ecademy]
