Hiding Chrome’s intranet redirect detector requests (aka weird requests) in Fiddler

Tuesday, September 15, 2015

This morning I saw this Tweet by Eric Lawrence, the creator of Fiddler: #lol "Fiddler periodically receives alien communications" http://t.co/IZh0UrkbEPThis is a well known trick of Chrome, which you can read about here, and see its source code here. Question is, now that we know what those “alien” requests are, how do we get rid of them in Fiddler’s session list? 1. Open Fiddler’s script (either through the FiddlerScript tab, or in the menu Rules->Customize Rules…) 2. Locate the OnReturningError method, and uncomment it 3. Place the following code in the method: if (oSession.LocalProcess.StartsWith("chrome") &&...

Wrapping up October’s conferences

Monday, October 14, 2013

It’s mid-October and I’m already warn down after two weeks of conferences. My October began in Las Vegas with DevConnections where I had a workshop and four sessions, continued with a 72-hour stop back home in Israel for some father-son time (with my son of course, not with my father), and then another week in London with Software Architect where I had a workshop and a session. Now I’m back home, relaxing, working, and preparing for my next conference in December, this time in Israel at the SDP (Sela Developer Practice) conference. In case you didn’t attend my...

Speaking at DevConnections 2013

Monday, August 26, 2013

If you’ve read my post from last week, you know that I went off the grid for 8 months, mostly because I was working on authoring yet another course for Microsoft (20487 – Developing Windows Azure and Web Services), but also partially because of my new baby boy, who made sure my laptop stays closed when I’m at home. Now that my baby is a couple of months old, I can start my conference rotation for 2013, starting with DevConnections. Speaking at DevConnections is going to be a great experience for me, for several reasons: ...

Wow, a conference that lasts 8 days, that a first. So here’s the gist of what I taught in 5 of these days: What’s new in WCF 4.5 In this 1-hour session I covered some of the important new features of WCF 4.5, such as Intellisense for configuration, UDP and WebSockets bindings, and improved support for streaming and compression. Debugging the Web with Fiddler In this 1-day tutorial we saw how to use Fiddler to debug, test, and...

Two months speaking spree

Friday, October 5, 2012

If you’ve been checking my blog in the last couple of weeks, you might have noticed I haven’t been posting much. In the past two months I have been traveling around the world, speaking in conferences and local user groups. So to sum up this intensive, fun times, here’s a list of all conferences I visited and links to all the material I showed. What’s new in WCF 4.5 Building scalable, low-latency web apps with Windows Azure Embracing HTTP with the ASP.NET Web API ...

What’s new in WCF 4.5? WebSocket support (Part 1 of 2)

Thursday, March 1, 2012

This is the 11th post in the WCF 4.5 series. The previous post was about the new UDP transport support, and this new post is also about new transports – the WebSocket transport. This post is part 1 of 2. This post will be about the WebSocket support between .NET apps using WCF (SOAP-based), and the next post will be about using WebSockets between browsers and WCF (non-SOAP). Previous posts: 1. What’s new in WCF 4.5? let’s start with WCF configuration 2. What’s new in WCF 4.5? a single WSDL file 3. What’s new...

My Fiddler Session in Sela’s Dev Days

Thursday, June 30, 2011

Today was my last session in the Dev-Days conference, and this time it was about Fiddler. In this 1-day session we saw how Fiddler can be used to sniff communication, use it as a reverse proxy, manipulate the communication, and how to extend Fiddler with your own custom inspectors and request/response tampering code. We also saw several extensions for fiddler such as the SyntaxView, the request code generator, and the FiddlerScript utility that enables you to edit the Fiddler’s script using intellisense. You can download the presentation and the code samples (including two sample inspectors I...

IE9 RC allows fiddler to get localhost calls

Sunday, March 6, 2011

For the last couple of days I noticed something odd about my installation of Fiddler – it suddenly started to show me localhost calls when I debugged web applications. At first I assumed that a new version of Fiddler which I’ve installed recently fixed the oldest problem of fiddler, but apparently it’s not Fiddler who should be given the credit, but rather IE9 RC. With the new release of IE9 RC, a new ability has been added – proxy loopback traffic. You can read more about this feature here. Edit: There are several ways...

WCF, Silverlight, Fiddler ומה שביניהם

Thursday, January 6, 2011

  שלמה העלה פוסט היום בנושא Binding ב-WCF ובו הוא הציג כיצד ניתן להשתמש ב-Custom binding ליצירת שירות שמעביר הודעות בינאריות מעל HTTP. שלמה ציין שמקרים אלו נתמכים במצבים בהם גם הקליינט וגם השירות כתובים בדוטנט – אחד המקרים האלו הן אפליקציות Silverlight שברוב המקרים מתקשרות עם שירותים באמצעות BasicHttpBinding (כי רוב ה-bindings האחרים לא נתמכים). במקרים כאלו ניתן לשפר את הביצועים של תעבורת הרשת ע”י הגדרת custom binding המשלב binary encoding כפי ששלמה הציע ובכך לאפשר ל-Silverlight ולשירות ה-WCF להעביר הודעות יותר מהר ביניהם. הבעיה היחידה שקיימת כאשר עובדים בצורה זו היא התמודדות עם שגיאות בתעבורה. בגלל הבעיות המוכרות של...
