A1 - you need to build the registry path.
A2 - don't' bother with this unless you first determine *what* is too big for 
the compression filter.

Make sure you *don't* include images as compressible entities - this is wasted 
effort more often than not, since the file format for all modern image formats 
already compresses them.

Subject: [isalist] Compression Filter memory problem

http://www.ISAserver.org
-------------------------------------------------------

System: ISA 2006 EE with 4gb mem

Receiving the following 2 errors:

1) The Compression filter cannot handle a response because the allocated
memory currently used for compression reached its limit. The memory
allocated for compression is specified by the following  registry values
under the HKLM\Software\Microsoft\RAT\Stingray\Debug\W3Filter key:
COMPRESS_MEMORY_ALLOC_MBYTES (by default, 256) and
COMPRESS_MEMORY_POOL_BLOCKS (by default, 200).


2) ISA Server was unable to compress a response body from
rafblibrary.org because the following error occurred: Unspecified error
. This error generally occurs because the available memory is
insufficient for completing the compression process.


RAT\Stingray\... key is not in the registry.


The log indicates that some external www users are able to hit the
internal web sites without compression.  The log also indicates that the
www users that cannot hit the internal www are using compression.

Any ideas on this?
