easiest way to find the HTTP include in a HTTPS throwing security warning?

Question

I often have to go into other people's work to make modifications for short-term contracts and a lot of times I have to deal with security warnings throwing in IE because something is including HTTP content from maybe an image, or css or whatever, onto a HTTPS secure page.

I was just curious if there is a well known program or service that will scan a URL and come back with exactly what is coming from HTTP instead of HTTPS on a page?

I use fiddler, but for reasons having to do with my own inadequacies, I find the program difficult at times, and am un-able to zero in on the offending content in a timely manner.

Any advice from the true pros?

Answer 1

Using Fiddler:

In main menu > Tools > Fiddler options, tab HTTPS, uncheck Capture HTTPS CONNECTs. Then, in main menu > Rules, check Hide HTTPS CONNECTs.

This way, the only thing you'll see in your Fiddler capture will be the HTTP requests and responses (without the HTTPS requests or CONNECTs getting in the way).
