+ serve additional requests.
+ This does not necessarily mean that something went wrong and
+ information about tainted sockets is only logged if connection
+ debugging is enabled (debug 2).
+
+
+ For example server sockets that were used for CONNECT requests
+ (which are used to tunnel https:// requests) are considered tainted
+ once the client closed its connection to &my-app;.
+ Technically &my-app; could keep the connection to the server open,
+ but the server would not accept requests that do not belong to the
+ previous TLS/SSL session (and the client may even have terminated
+ the session).
+
+
+ Server sockets are also marked tainted when a client requests a
+ resource, but closes the connection before &my-app; has completely
+ received (and forwarded) the resource to the client.
+ In this case the server would (probably) accept additional requests,
+ but &my-app; could not get the response without completely reading
+ the leftovers from the previous response.
+
+
+ These are just two examples, there are currently a bit more than
+ 25 scenarios in which a socket is considered tainted.

+ While sockets can also be marked tainted as a result of a technical
