Guidelines
Filters differ from transforms in that filters produce no output. Filters are generally
used to propose conditions against which a candidate document is evaluated. They
result in an accept or reject decision.
Filters are implemented by processing policies. A processing policy enables
DataPower services to select an appropriate style sheet with which to filter or
transform an input document. The selected style sheet can be used in conjunction
with, or instead of, processing instructions contained within the input document.
Refer to Appendix B, "Processing Policy procedures," on page 999 for procedural
details regarding the creation and implementation of Style Policies.

input-filter
Specifies a decompression algorithm to apply to all incoming traffic before any
other processing occurs.
Syntax
input-filter {zip | pkzip | none}
Parameters
zip
pkzip Decompresses all incoming traffic with the PKZIP algorithm.
none
Guidelines
Use this command only if you are certain that all incoming traffic is compressed
with the selected algorithm. Attempts to decompress non-compressed data will
result in data corruption.
Identifies the context that contains the document to be filtered. Use INPUT
to specify the initial policy input, that is the original client request or
server response.
Identifies the XSL style sheet to filter the source document. Takes the form
of a URL or a variable that expands to a URL.
