PM03333: ENABLE POST DATA TO BE READ MULTIPLE TIMES.

Fixes are available

APAR status

Closed as new function.

Error description

It is not possible to read post data both as parameters and
either using a InputStream or Reader. The second read will not
receive any data. This may occur, for example, when a filter
reads one or more parameters and a servlet tries to read the
post data as an InputStream, or vice-versa.

* RECOMMENDATION:                                              *
****************************************************************
As part of request processing, post data may be read either as
parameters or using an InputStream or a Reader. However
whichever method is used the WebContainer does a destructive
read of the data such that the data may be read only once for
a given request.

Problem conclusion

The WebContainer has been modified to enable multiple reads of
post data when the following WebContainer custom property is
set to true:

com.ibm.ws.webcontainer.enableMultiReadOfPostData = true

With this property set the post data can be read multiple
times as either an InputStream or Reader, and as parameters.

Further, to enable post data to be re-read from the beginning
using an InputStream or Reader, or as Parameters, the following
sequence must be followed when using a Reader or InputStream:

1. obtain the InputStream or Reader
2. read data
3. close the InputStrean or Reader

Note that internally the WebContainer completes this sequence
when reading parameters.

If either steps 1 or 3 are not observed the next read of the
post data will not be reset to the beginning of the data.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.31 and 7.0.0.9.  Please refer to the
