Thanks... Would turning on allowXML have any potential to negatively affect the member profiles as long as they are not used individually outside the metaProfile...
No, it's just a perm flag. Turning it on just makes things less restrictive. So someone could request results in xml format instead of html if they knew the appliance url syntax. There's no real danger in allowing xml except to make it slightly easier for others to fetch and republish your results with their style or name.
Not sure what you're answering here. There were 2 questions above. "no it doesn't" doesn't sound like an answer to either of those.
Yes, there is extra info in urls from meta searches. And when trying to debug odd behavior it's best to eliminate as many unknown variables as possible. People's proxy scripts have been known to mess up plenty of applications for various reasons. We can only support direct usage of the appliance, not people's own proxy scripts.
