Very large LAR files can be lost just at the very end of export due to OutOfMemoryException

Description

  • Set the portal's Heap to 4GB

  • upload more than 1GB of files to the doclib

  • export a LAR of the site (including doclib)

In all likelyhood, an OOME will occur when trying to send the resulting LAR file back over the http response.

The issue is that the StripFilter has not been disabled and will wrap the response in a StringServletResponse, which buffers the output in an UnsyncByteArrayOutputStream.
