Bug #: 51872
Summary: request.getRemoteAddr() sometimes returning IP address
from the previous request
Product: Tomcat 7
Version: 7.0.20
Platform: PC
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: Connectors
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
request.getRemoteAddr() sometimes returning IP address from the previous
request. We have compared the IP address returned from the getRemoteHost() and
from the headers with getRemoteAddr() and getRemoteAddr is returning wrong IP
address. We believe that this may come from the "pooled" request objects where
it is sometimes sees the previous value of the remote IP. The problem doesn't
occur all the time.
We are heavily relying on the getRemoteAddr to verify the remote client for
some of our authentication. Can this be fixed?
