Is it possible to get raw HTTP requests and responses in my own Explorer Bar

I wanna develop an Explorer Bar for IE to interceptRAWHTTP requests and responses. These includes raw data initiated by the URL entered in IE address bar, and images' URLs within that main HTML file. Is it possible?

Possible, yes. HTTPExplorer and a few other similar toolbars do this. There are several techniques: 1> Detours, a technique for remapping function calls at runtime, 2> Using a pluggable namespace handler 3> Using a proxy.

#1 is quite tricky and prone to breaking with each new version of IE. You can potentially use this to view SSL traffic.

#2 is a bit more straightforward, but it's still non-trivial. You can potentially use this to view SSL traffic.

#3 is relatively straightforward, but it is hard to use this technique to view HTTPS traffic.

There are many off-the-shelf packages which already do this, so you may want to consider if any of them do what you're looking for.

I'm always on the lookout for feature-suggestions for my HTTP Debugger, named Fiddler.

Hi, I am interested in doing something similar which is to

- list the images/css/js... files that are a part of a page

- list the time it took to download them

- list whether the item was served from the cache or not

- display the http headers associated with that response

...

Eric, you mentioned a few possiblities above. Regarding the namespace handler, could you share any pointers on it. I saw links for implementing a pluggable protocol handler but it seems that with the namespace handler I could listen to events on a protocol of interest (http).

Also could you elaborate on the option of using a proxy. Not sure what you mean by that. Thx.
