Why do you need an HTTP Viewer or Sniffer?
All web applications make extensive use of the HTTP protocol
(or HTTPS for secure sites). Even simple web pages require the
use of multiple HTTP requests to download HTML, graphics and
javascript. The ability to view the HTTP interaction between the
browser and web site is crucial to these areas of web
development:
- Trouble shooting
- Performance tuning
- Verifying that a site is secure and does not expose sensitive
information
How can HttpWatch help?
HttpWatch integrates with Internet
Explorer and records detailed information about HTTP as you
access a web site or application. If you access a site that uses
secure HTTPS connections, HttpWatch automatically displays the
decrypted form of the network traffic.

Conventional network monitoring tools just display low level
data captured from the network. In contrast, HttpWatch has been
optimized for displaying HTTP traffic and allows you to
quickly see the values of
headers, cookies, query strings and
more...
HttpWatch also supports non-interactive examination of HTTP data.
When log files are saved, a complete record of the HTTP traffic is
saved in a compact file. You can even examine log files that your
customers and suppliers have recorded using the free
Basic Edition.

Why HttpWatch?
Seven reasons to use HttpWatch rather
than other HTTP monitoring tools:
-
Easy to Use - start
logging after just a couple of mouse clicks in Internet
Explorer. No other proxies, debuggers or network sniffers
have to be configured
-
Productive - quickly
see cookies, headers, POST data and query strings without
having to manually decode raw HTTP packets
-
Robust - reliably log
thousands of HTTP transactions for hours or days while
tracking down intermittent problems
-
Accurate - HttpWatch
has minimal impact on the normal interaction of Internet
Explorer with a web site. No extra network hops are added,
allowing you to measure real world HTTP performance
-
Flexible - HttpWatch
only requires client-side installation and will work with
any server side technology that renders HTTP pages in
Internet Explorer. No special server-side permissions or
configurations are required - ideal for use against
production servers on the Internet or Intranet
-
Comprehensive - works
with HTTP compression, redirection, SSL encryption & NTLM
authentication. A complete automation interface provides
access to recorded data and allows HttpWatch to be
controlled from most popular programming languages.

Uses of HttpWatch
HttpWatch is used in a wide variety
of companies and industries for tasks such as:
-
Testing a web application to
ensure that it is correctly issuing cookies or setting
headers that control page expiration
-
Finding out how other sites
work and how they implement certain features
- Checking the information that
Internet Explorer is supplying when you visit a site
-
Verifying that a secure web
site is not issuing sensitive data in cookies or headers
- Tuning the performance of a
web site by measuring download times, caching or the number
of network round trips
-
Learning about how HTTP works
(useful for programming and web design classes)
-
Allowing webmasters to fine
tune the caching of images and other content
-
Performing regression testing
on production servers to verify performance and correct
behavior
