How can we map a particular request between the wso2carbon.log and the HTTP access log?
IMO, we should generate this Correlation ID from a custom valve and add that as a request attribute, and then extend the Access Log valve to print that ID in the HTTP Access Log as well. (I haven't tried this, but I believe this approach is feasible) Also, by doing this way you don't have to individually add the filter to each webapp in the product, because valves get engaged for all the contexts. WDYT?
