This is a MIB for managing Application Acceleration System(s).
This MIB includes instrumentation for providing the
performance statistics and status of the condenser which is
the core of the Application Acceleration System.
A condenser is a software accelerator that applies several
optimization techniques to accelerate Web application access.
The condenser application accelerates and optimizes any HTML or
XML-based application over HTTP resulting in response
time improvements and decrease in bandwidth requirements.
This application shall reside in a content switching module or
appliance.

Acronyms and terminology:

HTTP 

In this MIB it refers to both secure ('HTTPS') as
well as non-secure ('HTTP') web traffic.

IMS 

If-Modified-Since is an HTTP request type.
The If-Modified-Since request-header field
is used with a method to make it 
conditional: if the requested variant has not
been modified since the time specified in this field,
an entity will not be returned from the server; instead,
a '304' ('not modified') response will be returned without
any message-body.

Delta 

It is the ability of condenser to dynamically
update client browser caches directly
with content differences, or deltas,
resulting in faster page downloads.

FlashForward 

FlashForward is a object acceleration technology that
eliminates network delays associated with embedded cacheable
web objects such as images, style sheets, JavaScript files, etc.
FlashForward object acceleration places the responsibility for
validating object freshness on the condenser, rather than on
the client, making it more efficient. With FlashForward, the
client never needs to validate the freshness of browser-cached
objects with the origin server, thus significantly accelerating
page downloads, and reducing both upstream and downstream
traffic associated with object validation requests. 

Transformation 

It is the change applied on the incoming 
web traffic, as part of specific 
optimization method like delta or
flashforward, to achieve web traffic
acceleration.

Objects 

All the non-textual embedded components of a web 
page are referred to as Objects in this MIB.

Condensable 

It refers to all objects that can be subjected 
to optimization by condenser.

Non-Condensable 

It refers to all objects that cannot be
subjected to optimization by condenser.
