Hello,

I am trying to create an extension for Fiddler, but my problem is that I cannot do drag and drops from the Session View into the DataGridView. 

When I implement the DragEnter method of the DataGridView I only see the dragged object as a DataObject and I cannot convert it to Session type and it does not contain any text.

I would like to access the URL of the session.

I could not find any documentation and no open-source plugins to check how its done in other extensions like the AutoResponder.

Could you please tell me how to do this?

Cheers,
Zsombor

How can I completely hide Fiddler and prevent it from appearing in the Notification area? I don't want other users to notice. And I'm not talking about "Choose Hide icon and notifications".

My Goal:Append +test1+test2+test3 to query, then before data reaches the client's web browser replace +test1+test2+test3 with an empty string.

To append string to query, I used this code

static function OnBeforeRequest(oSession: Session) {

if (oSession.uriContains("www.youtube.com/results?search_query="))
{
var str = oSession.fullUrl;
var sAppend = "+test1+test2+test3";
if (!oSession.uriContains(sAppend))
{
oSession.fullUrl = str + sAppend;
}
}

Everything worked fine, but the problem started after I added this code

static function OnBeforeResponse(oSession: Session) {

if (oSession.HostnameIs("www.youtube.com") && oSession.oResponse.headers.ExistsAndContains("Content-Type","text/html")){
oSession.utilDecodeResponse();
oSession.utilReplaceInResponse('+test1+test2+test3','');

Instead of appending to search_query=, it gets appended to &page=

I'm pretty sure oSession.utilReplaceInResponse is responsible for the problem.I really need help.

Thank you.

Hi Telerik, Eric, 

Thanks again for Fiddler and FiddlerCore, they're amazing tools.

I and others have asked for years for a NuGet package for FiddlerCore. The lack of such a package is preventing the release of  https://github.com/mausch/ElmahFiddler/issues/4 , complicating the tests for https://github.com/Azure/azure-storage-net#test-dependencies and probably causing many other issues for other projects, open source or not.

So now that Telerik bought Fiddler, is there any chance of releasing FiddlerCore as a NuGet package? Telerik already publishes a lot of NuGet packages so it would make sense to publish FiddlerCore too.

Thanks,
Mauricio

The app that I am debugging is doing loads of PUT requests over (decrypted) HTTPS and sometimes is PUTting a file that is 4.45GB. Part way through the large PUT request Fiddler shows me this message:

---------------------------
Uncaught Exception in Session #36250
---------------------------
Sorry, the .NET Framework (and Fiddler) cannot handle streams larger than 2 Gigabytes.

Type: System.Exception
Source: Fiddler
   at Fiddler.PipeReadBuffer.Write(Byte[] buffer, Int32 offset, Int32 count)
   at Fiddler.ClientChatter.ReadRequest()

Fiddler v4.4.9.2 (x64 AMD64) [.NET 4.0.30319.18444 on Microsoft Windows NT 6.1.7601 Service Pack 1] 



Is there a way of working around this 2GB restriction?

Hi,

I am trying to use fiddler core libraries on Windows Phone 8.1

When I include them in project I receive error like 'Type universe unable to resolve 'System.Windows.Forms'

What I have figured out is we cannot use Desktop versions of dll for Windows Phone platform.

Is PCL (portable compiled libraries) for fiddler core?

Hi,
I use Fiddler a lot to debug an application, and Fiddler Core for my own application. Both have the problem that when I start capturing and decoding HTTPS traffic with the fiddler certificate that eventually (hours to days) my PC has no internet connection whatsoever. My browsers report that DNS lookups failed, Chrome sometimes says "ERR_NAME_RESOLUTION_FAILED", and so on. The only solution to restore connectivity is to stop capturing https, remove the certs, and restart the PC. There are also less severe cases when I only lose internet when I close Fiddler. All of this is bothersome for me and unacceptable for my app. Is there anything I'm doing wrong? I leave the default options in Fiddler except for the https capturing and decrypting. I use an auto-updated win 8 and auto-updated fiddler 4.4.9.2. I am on a home LAN behind a router/modem.

Hi,

When I enable "SimulateModem" , set oSession["request-trickle-delay"]="64", and oSession["response-trickle-delay"]="64", I could get the latency about 120ms, but the download speed will be no more than 15KB/s. 

I want to simulate the network with 300ms latency and 3mbps bandwidth.  How should I do? 

Thanks

I'm trying to record a website so that I can view it when I'm offline.
Obviously the default options of recording from the various browsers don't work, so I wanted to do this with Fiddler.
I have gotten to a point where I can just surf the page I want, and then copy all of the requests and urls to the right side, and than when I play it back, the page shown to me is the page from the Fiddler recordings.
However, the iFrame part gets a "404 error" and so, I can view the whole page, but I can't seem to capture the iFrame.
Is there any way around this?

For example: I typed "whose line is it anyway" in google,and noticed many torrent sites in the search results and i want to block them completely.Now,how do I request Fiddler to exclude the word "torrent",cause in the "Request Headers" section,the text view is empty
