Extension for Fiddler, to display the session information in a TreeView panel instead of the default ListBox, so it groups the information logically based on hosts, folders, etc...
If you need to capture http traffic there are several tools out there that can help you with this task, and a really good one is
It's really flexible and, best of all, it's free. :-)
The only thing you might be a little bit annoyed with is that, when analyzing a site that performs lots of calls, you might end up with a screen like the following:
which is a great amount of information but it's a bit complicated to locate exactly the session you're looking for (sure, you can sort the ListView and such, but that wasn't
for me. :-D).
So, to address this issue I have created an extension that displays all the sessions in a TreeView, so the hosts, folders and calls are organized in a tree structure, much faster to locate what you want and to collapse entire sections of data you don't
need. The results for the same captured data can be seen in the next screenshot:
To switch between the two views, a new menu entry has been created in the top level menu called
where you can activate or deactivate it (shortcut CTRL
Integration with Fiddler is not 100%, since I first created this extension to be able to locate sessions in a more efficient manner. You can right-click on a session and the original Fiddler context will show up, although some options will not be usable or
have any meaning. I'm sure other stuff might not work as well, but again my goal was just to make it
for my own needs. ;-)
For instance coloring a session will in fact color it in the ListView, but nothing will happen in the tree.
We can however reissue sessions, save them, etc...
In order to install this extension you'll need to copy the compiled assembly .DLL into your
folder (or \Program Files\Fiddler2\Scripts
to make it available to all users on the machine). After that, you'll need to restart Fiddler if was already running.
Right now, there are issues in the way sessions are deleted, because the only way to effectively delete a session is by choosing the
option from the tools menu as shown in the selected screenshot:
All the other ways to delete sessions (even from the context menu) will wipe them out from the ListView but
from the TreeView, so you might get out of sync (not a huge deal since you can re-sync by using the above option as well). The biggest roadblock is that the ListView won't fire an event when items are removed from it, so I'd need to implement
an additional mechanism to fix it (btw, that's the reason there are some work-in-progress sections in the source code).
But other than that the extension is fully usable and I thought some of you might find it useful too.
Of course, you're free to download the code and if you want to extend it further or have some ideas let me know. :-)
Thanks to Eric Lawrence for some suggestions, I've added double-click to expand/collapse all child nodes at once (where clicked) and to keep the selected session when losing focus off the TreeView.
