Hi
My answer was not inrelation to response time really. It was related to "I have paid for a Support membership". We just don't sell that, that's all.
As for the real problem:
1. The problem that I am facing is that links on the website - or posted externally go to the wrong page. I understand that VM does a cookie check, but the cookie check should happen behind the scenes, not send the visitor to an incorrect page on the site.
First I'm sure you understand this is a VM issue, not sh404sef. Second, there is technically absolutely no way to do otherwise than oing this redirect. It is not specific to VM, even Google does it. I am pretty sure it can be disabled in VM backend, but I personnally don't thin it is a good idea.
Second, I don't understand twhat you are saying. You click on a link in Google search results -which does not have /vmchk/ in it, thanks to sh404sef

- and you get on the correct page, with the correct product showing. The only difference is 5 letters more showing in the address bar!!!
2. When people hit this incorrect page, they are going back to Google search, as it is not the page they wanted. I am losing visitors.
I am not sure people will see they are on an 'incorrect page'. The difference between the 'good' page and the 'bad' one being only 5 letters in the address bar, I'd be surprised if anyone notice. As a matter of fact, I have to say you're the first to report that sort of thing. I'd suggest you discuss that with VM team and see if anyone has reported loosing visitors because of that. I would thought there is actually noway to tell why visitors would bounce back from a page, whether it's because of those 5 letters or for some other reason.
