I find myself applying the same filters again and again on each launch of Fiddler (I mean the filters listed below the list of requests).

I think it would be really great if you could allow the restoration of previously applied filters (e.g. by having a save/load filters option).

Also, allowing to filter out by "Request Method" would be great too.

Congratulations on this tool, by the way.

It is really great. :)

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

FWIW, one reason that the RAW Inspectors are so rough is that I never used them, even though I suspect telemetry would show that they're pretty popular.

The Raw Inspectors are among the few remaining Inspectors that don't override the AssignSession() method, but should. That will allow setting the Headers, Body, and ReadOnly state in one shot instead of performing three updates. This should take no more than a few minutes for Telerik to change.

If you have auto save turned on and a web socket initiates inbetween the save interval, messages captured during the interval are saved to the "_w" files in the saz file.

After the autosave is triggered, captures that happen on the same session are no saved in subsequent autosaved saz files.

Tools > Options > Scripting has a new Language Dropdown.

It should be a DropDownList instead of a dropdown, otherwise, any character the user types causes a popup alert and the user can be left with a garbage value.

Further, there probably shouldn't be an explicit warning that a restart is required, as a great many options on the Options dialog require restart and showing this warning for only one of them may be misleading.

Steps to reproduce:

1. Open Fiddler

2. Go to Tools > Telerik Fiddler Options > HTTPS

3. Click the TLS Protocols

4. Fiddler hangs and after a minute or so crashes

Note, supporting permessage-deflate without the

    client_no_context_takeover
    server_no_context_takeover

parameters (meaning that context takeover is allowed) likely would be pretty tricky because I don't think the DEFLATE code inside Fiddler is able to reuse a single compression context across multiple operations.

https://bugs.chromium.org/p/chromium/issues/detail?id=653691 (https://bugs.chromium.org/p/chromium/issues/detail?id=653691#c5)

Chrome 57 won't accept certificate chains that contain SHA-1 within them, so we need to be sure that Fiddler/FiddlerCore default to SHA-256 everywhere. We also might consider whether we should detect that the user has old Fiddler-generated SHA-1 certificates cached and if so, clean those up and generate a fresh cert using SHA-256.

Recently Fiddler has taken to flooding OutputDebugString with the message (from DebugView):
[5936] Telerik Analytics Monitor ***** ERROR *****: Recovered session data could not be sent: 0 Request failed: NameResolutionFailure: No se puede resolver el nombre remoto: '27006a8622544e43b0da60db63bd66ba.monitor-telerik.com (http://27006a8622544e43b0da60db63bd66ba.monitor-telerik.com/) '
There seem to be about 8 messages a second. This makes debugging other applications that use OutputDebugString almost impossible if Fiddler is running.

Otherwise, the response is illegal, because you MUST not send a C-L if you're sending Transfer-Encoding:Chunked

I'm running the latest Fiddler's mono version and it would be great to be able to capture WebSockets traffic on this version. I know it is possible on the Windows version.
