Using Fiddler to check IIS Compression

How do I see if IIS Compression is working using Fiddler? I have a page that, when viewed through Port80Software or GID Network's tool it appears to be coming across compressed. However, when I watch the call in Fiddler, I see the 'Accept-Encoding: gzip, deflate' in the request header, but I don't see the 'Content-Encoding: gzip' or 'd...

How to get Fiddler to report HTTP connections on a local PC

I have a client and a server and they are both on the local box and they speak web services. How can I get Fiddler to report these connections? It only seems to want to report connections to other PCs. NOTE: I actually found the answer. http://www.fiddler2.com/Fiddler/help/hookup.asp#Q-LocalTraffic ...

How can I debug "/mysite/null" resource request?

I've been trying to work out why our pages load slowly, and one thing I've noticed in Fiddler is that each page load for /mysite/mypage.aspx brings with it a request for GET /mysite/null HTTP/1.1, resulting in a 404 error. I'm guessing this 404 error on every page load is slowing the site down even further, are there any ways of debugg...

Is it possible to redirect a url to another using a webproxy ( such as fiddler )

I'm trying to parse a WSDL file which is in another server but has hard codded "localhost" all over the document. When I fetch it, obviously the program complains "connection refused" because nothing is running in my machine. My question is: Is it possible to use a webproxy ( such as fiddler ) to redirect those localhost request to m...

Why does the performance of the HttpWebRequest object improve while using Fiddler?

I'm getting some very strange behaviour with HttpWebRequest I hope someone can help me with. I have a console app which does some aggregation work by by using the HttpWebRequest object to retrieve the contents of a target website. Due to the nature of the requirement the app is multithreaded and attempts to make anywhere between 10 and 3...

IE7 stops making network requests after a while

Our (asp.net) system is part of a larger system. It is launched via this larger system from javascript that does a window.open call to open a new window. (aside, authentication data etc is passed into our system via an encrypted query string parameter) When testing with IE7 (unfortunately the organization has standardized on this) the...

HTTPS C# Post Problem (with Fiddler)

Hi :) Basically I have this code below & the last step FinalStepGetReportData() throws an exception on return (HttpWebResponse)request.GetResponse(); if fiddler is switched off? All else works when Fiddler is OFF except this last step. When I turn Fiddler on the final step works ? Any ideas? I am banging my head against the wall. Th...

Apache on Windows and Fiddler

I need to monitor HTTP traffic in my dev env which is PHP/Apache/Windows. But Apache seems to refuse the HTTP requests coming from fiddler which sits between the browser and Apache. Error is No connection could be made because the target machine actively refused it I suppose there should be some configuration on Apache which allows traf...

Fiddler - letting localhost pass through (not debugging localhost) how?

I need to use fiddler to block traffic to a site using autoresponder when working with localhost (as localhost). My question is how to make fiddler transparent to localhost traffic. I don't necessarily need the localhost traffic to go through fiddler, I just don't want fiddler to block it. I did it in the past after some research but un...

Why would IE/Fiddler see different cookie setting/deletion from Chrome and FF/Live HTTP Headers?

I have a partly inherited web application in PHP and after poking around with Fiddler I have a little more data than before. The problem I'm trying to solve is unwanted logouts on IE6/8 but not FF/Chrome. If a user clicks between different pages, the login data cookies vanish. The behavior is different in FF vs. IE, and the reported inf...

Fiddler 2 Wipes My Internet Explorer Proxy Settings

I just started using Fiddler 2 to create request objects for REST,JSON, and SOAP based services that I have been creating. It has worked great so far. The problem came when I attempted to use some of my company resources through Internet Explorer. I was getting some sort of a DNS error, which I realized was happening because my proxy s...

Includes and persistent storage in CustomRules.js of Fiddler

I've been using Fiddler for a few days now, extending CustomRules.js with my own logic. However, the file is becoming quite heavy (it's fairly heavy to begin with). I'm not very familiar with .NET or JScript, but I would like to be able to split CustomRules.js into several smaller files that I can just include into CustomRules.js. Is thi...

Fiddler slows down my browsers

Working with fiddler on 2 pcs. On my better performing pc fiddler slows down both browsers (firefox and IE7) significantly. any suggestions would be appreciated thanks, Ido ...

Generating PDF, error with IE and HTTPS

I am streaming a PDF to the browser in ASP.NET 2.0. This works in all browsers over HTTP and all browsers except IE over HTTPS. As far as I know, this used to work (over the past 5 years or so) in all versions of IE, but our clients have only recently started to report issues. I suspect the Do not save encrypted pages to disk security op...

Is there a Fiddler plugin for binary XML?

Fiddler has many useful extensions. However, I can't find one that understands WCF's binary-encoded SOAP envelopes. (Content-Type: application/soap+msbin1) Suggestions for comparable (non-Fiddler) tools are welcome too. ...

View WebRequest XML

Hello, I'm having a strange issue - I saw a similar post on this forum, but it didn't have an answer. Long story short, I am sending an HttpWebRequest using C# to a web service (stubs were created by adding a web reference in Visual Studio 2008, .NET 2.0) which breaks with the following message: "Unable to parse the incoming request". ...

HttpWebRequest to server that does not allow chunking does not work

I have some C# stubs to a Java web service (Https) (created in Visual Studio 2008, .NET 2.0). The server does not allow requests to be chunked. I was able to set sendChunked to false in the HttpWebRequest. When I call web service methods which have very little data going across the wire they work fine. However, when I send requests whic...

Can I start fiddler from C#?

I'm trying to build a C# application, which uses Fiddler. I saw in the documentation somewhere, that there is supposed to be a function Fiddler.Application.Start or something like that. However, I can't find it. I'd prefer not to write a fiddler extension, because I think it will be more powerful to integrate fiddler into my app. Does an...

Fiddler/Firebug for Adobe AIR?

How does one inspect the HTTP traffic in Adobe Air? Obviously because it's running outside of a browser you can't use firebug ... I've tried this link text but it doesn't work either... (nothing shows up in the log). I also don't really want to pay for a program. Any ideas? ...
