Packaging Fiddler change into a .dll?

[Drew]

Is there some sort of way we can package a Fiddler replacement rule into a standalone .dll and place it in the program's folder to have the same effect as Fiddler changing it without having Fiddler installed on a computer?

Hello, Drew--

What you're describing is an application based on FiddlerCore. FiddlerCore allows you to build applications with Fiddler-like functionality without any of the UI.

See http://www.telerik.com/fiddler/fiddlercore for details.

It's not necessarily for a program we made. We have a program that requires an internet connection to run, but all that it does is fetch some cloud settings. With Fiddler, we were able to feed it a copy of those settings whenever they were requested, removing the need for an internet connection. However, installing Fiddler on every computer in addition to the program and then running Fiddler whenever the computer is not hooked up to the internet can be a pain. Is there any way to have Fiddler-like functionality in programs not made by us?

I'm not sure I understand what you're asking.

Q: "Can we modify someone else's program to integrate Fiddler-like functionality directly into it?"
A: Well, technically yes, but that seems like a lot of work and it may be illegal, etc.

Q: "Can we make a program that intercepts web requests from other programs, just like Fiddler does?"
A: Yes, that's what FiddlerCore is for. http://www.telerik.com/fiddler/fiddlercore

The first of the two.

""Can we modify someone else's program"
"A: Well, technically yes, but that seems like a lot of work and it may be illegal, etc."

Not necessarily breaking into the code and modify it directly, but build a standalone Fiddler dll or something included in the program's directly which is then loaded by the program that intercepts web requests without actually having Fiddler installed. Legalities aside (even though I don't recall anything prohibiting this in the licensing terms), is there existing functionality to accomplish this?

Hello, Drew--

You can't make some other program just load your DLL (without writing a different program that causes this to happen). At the point that you're writing a different program, you're back to building an application on FiddlerCore.
