Fiddler, hands down! http://www.fiddler2.com/fiddler2/

    Will Fiddler intercept requests made to localhost? May 2, 2009 at 2:53

    Yes, Fiddler can also capture localhost traffic. May 2, 2009 at 12:28
  • couldn't get it to work, it just says fiddler failed to decrypt https, and the website just loads till infinty

Wireshark. Gets HTTP and anything else you want to look at (DNS, usually).

  • +1 Wireshark will get anything that's going through the net card. May 2, 2009 at 3:00

    While Wireshark will capture anything, Fiddler is specialized in looking at HTTP traffic. If you're going to look at HTTP / browser traffic, I'd definitely use Fiddler over Wireshark. May 2, 2009 at 12:29

    +1. A little known feature is that Wireshark is also capable of decrypting SSL-traffic if you have the receiver's private certificate. Extremely useful imo! May 28, 2009 at 12:01
  • @Commander Keen -- +1 Thanks, that's a great tip.

General HTTP traffic:

Fiddler (free)

Internet Explorer and Firefox traffic:

HttpWatch (crippleware & pay)


Recommend Fiddler and Fiddler2 [Mark. Rasmussen above], and another GUI http(s) capture that runs on MS Windows and 'other' systems.


Looks to have the same feature/functionality as Fiddler2, with the addition that it can run on non MS platforms (could be useful for some.)

The Sales Pitch?

WebScarab is a framework for analysing applications that communicate using the HTTP and HTTPS protocols. WebScarab has several modes of operation, implemented by a number of plugins. In its most common usage, WebScarab operates as an intercepting proxy, allowing the operator to review and modify requests created by the browser before they are sent to the server, and to review and modify responses returned from the server before they are received by the browser. WebScarab is able to intercept both HTTP and HTTPS communication. The operator can also review the conversations (requests and responses) that have passed through WebScarab

Some of the basic functionality of value to web developers, security reviews, in WebScarab include: (from their website)

  • Fragments - extracts Scripts and HTML comments from HTML pages as they are seen via the proxy, or other plugins

  • Proxy - observes traffic between the browser and the web server. The WebScarab proxy is able to observe both HTTP and encrypted HTTPS traffic, by negotiating an SSL connection between WebScarab and the browser instead of simply connecting the browser to the server and allowing an encrypted stream to pass through it. Various proxy plugins have also been developed to allow the operator to control the requests and responses that pass through the proxy.

  • Manual intercept - allows the user to modify HTTP and HTTPS requests and responses on the fly, before they reach the server or browser.

  • Beanshell - allows for the execution of arbitrarily complex operations on requests and responses. Anything that can be expressed in Java can be executed.

  • Reveal hidden fields - sometimes it is easier to modify a hidden field in the page itself, rather than intercepting the request after it has been sent. This plugin simply changes all hidden fields found in HTML pages to text fields, making them visible, and editable. Bandwidth simulator - allows the user to emulate a slower network, in order to observe how their website would perform when accessed over, say, a modem.

OWASP, the developers of WebScarab also have a number of other Open Source Projects relevant to reviewing website performance, functionality, security et. al.


justniffer It can capture all http traffic, produce apache log, save content as files, measure response time . etc.



nmap / zenmap from insecure.org


i link using packetyzer for capturing.

its free and it has a easy to use gui.



There is little know but rather good Microsoft product for this:

Microsoft Visual Roundtrip Analyzer

It's built on top of Microsoft's Netmon and provides an insane amount of detail. It shows http traffic, including all the packet transfer details and any related DNS requested performed. It also has a go at giving you advice on the results.

Oh did I mention that it's free?


Yes, fiddler2 is very handy. Took me a minute to find out that you can use ipv4.fiddler:/ instead of localhost:/ The tool is fast and stable on the first glimpse


You can also check this HTTP post or Get tool (free tool)


maybe you can try this iehttptools

  • Using a link is cool, but still write the essential parts of the link please.
