I – Observing HTTP Traffic from the Android device A Windows machine (physical or virtual) However in most of them the information was just partial and I had to struggle a bit to get it working on my side, so I decided to produce my own post on the topic. If you search for the topic on the web, you will find many resources, blog posts and questions about it, that’s what I did. We are going to see how Fiddler can be used to also watch web requests performed from an Android device.

Basically Fiddler runs on Windows and can be used to debug a desktop App performing web requests.

Telerik provides that great freeware named Fiddler, a powerful web debugger that can, among other things, log the http traffic. (One can also use it to include various Greasemonkey scripts in the received response, without using a Greasemonkey add-on, like to block Flash without installing any add-on.Hey Folks! Today we are up to some sniffing on Android, great! … What for? Well, if you develop Cloud-related Apps, I mean by that an App that is going to use a REST Web API, then sooner or later you may want to observe the http traffic on your device for debugging purposes.

transform: modify the response received by the web-server before it is sent back to Safari.

request modification: this can change the requested URL, send back a redirect response to the browser, or send text/html back to the browser.

global proxy: this sets the global proxy settings, and can test for e.g.

There are 4 types of scripts running inside GlimmerBlocker, and some objects are only defined for some of the script types: And though not true debugging, it also offers logging. But it can in fact modify both requests and responses. Of course it can block all kind of content, and transform responses before the browser receives them.

It seems that the free GlimmerBlocker can do part of the trick. If you don't know JS Bin, then first view the introduction video.)

(As for auto responders: the excellent JS Bin has a short video on how to use it to debug Ajax requests. That makes things much easier to read as most web servers will compress the data they send to a browser.

Note that Wireshark can decompress gzip or deflate encoded (compressed) things on the fly for you. Or, to limit to some server, use capture filter ' port 80 and host Like: # Show only 404: page not found (You may want to set the capture filter to ' port 80', to show all requests to that port, and responses from that port. However, unlike Fiddler, Wireshark does not let you change the data, and does not support things like auto responders, like Fiddler apparently does.įor Wireshark, see Hyper Text Transfer Protocol (HTTP) for some generic HTTP capturing information, and HTTP Packet Capturing to debug Apache, for some example display filters. When things get more complicated, I fire up my Wireshark packet sniffer. (Enable the Web Inspector through the preferences: Show Develop menu in menu bar.) Chrome and Firefox have similar tools. Likewise, in Safari the Resources pane of the built-in Web Inspector covers most of my needs as well. In Firebug, the Network Monitoring shows all requests and responses. Not what you asked, but in Firefox the Live HTTP Headers add-on is all I need if I want to edit and re-play requests, including changing the URL and the HTTP method.
