Hello All,
It's been longer than I'd want to really get into this, but now that I've got a start on it I'd like some feedback on the best way to deal with the pattern attribute. For the file it currently just uses a pattern like %h %l %u %t %r %s %b %{i,Referer} %{i,User-Agent}. The problem is that doesn't really provide a key for the value. What I'm currently using is that same pattern and using the ExchangeAttributeBuilder.getName() as the key. However if the value of getName() changes at some point the data would end up with a different key. This approach doesn't seem ideal.
One option would be to switch to some kind of property format type of thing like:
attributes={"remoteHost"="%h", "identityUsername"="%l"}
I'm not sure how user friendly that is though.
The other option would be to limit it to known exchange attributes, but that would require a change every time a new attribute is added to Undertow itself or we'd have to allow for some kind of custom attribute.
Any opinions are welcome. Ideally we want something user friendly that's going to produce consistent keys as that would be part of the structured data contract.
