Hi Gurus,



I am a new one to this fiddler tools, but I have an interesting question,

After setting up one evironment, the connection is not working between
client/server. Then I used fiddler as troublershooting tools, but I
found when I enabled the tracing, my connection is back, then I disabled
the tracing my connection is lost again.



Could I know how fiddler made such kind of effect



Thanks very much

Hi,

I've been searching around but haven't been able to find something that fixes my issue.
I'm trying to debug an issue on a production server. I had no trouble on windows 7 but on the new windows 8 laptop I'm not having any success.

The error that comes up is:
The Same Origin Policy disallows reading the remote resource.

This is in chrome and firefox.

The file I'm trying to respond with is on my desktop. You can see the settings I'm using in the attached fiddler.png.

Anyone have any ideas on what the issue could be?

Hello.
When specified upstream proxy becomes unavailable, Fiddler is showing this messages in "Tools > Fiddler Options > Gateway > Show Current Gateway Info" window:
---
WARNING: HTTP Gateway specified was unreachable and is being ignored.
WARNING: HTTPS Gateway specified was unreachable and is being ignored.
WARNING: FTP Gateway specified was unreachable and is being ignored.
---
As I understand, Fiddler is just skipping specified proxy and using system proxy instead.
Is there a way to make Fiddler drop outgoing requests in case of invalid upstream proxy instead of forvarding 'em through the system proxy?

Hi, I am new here and looking for advice.
I had a problem with my emails and was advised by bt to remove ie and re-install.
I did this but I somehow installed Rocket Tab. I have had problems since then, 2 of which are
1) when I try to start internet access, I get a message saying my proxy settings are invalid, and I have to wait a few minutes before I get connected.
2) When I try to send an email which has a link in it, bt.com will not send itas they have detected "suspicious activity on my account".

Some-one has since told me that Fiddler is used in Rocket Tab.
I have searched for fiddler in my programs but cannot find it.
Could anyone help me to resolve this?

I was using Fiddler to trouble a website on localhost IIS using https (requires https) and now I can't connect to the website without Fiddler running. If I close Fiddler I get an error "Your connection is not private" (NET::ERR_CERT_AUTHORITY_INVALID). I don't know what changed. I thought I added I cert exception some while ago which enabled me to bypass the error.

For example:

After I close Fiddler, Firefox displays this message "Firefox is configured to use a proxy server that is refusing connections." How do I make it work?

Thank you.

Hello,

I am missing this functionality in Fiddler2:

1. I click "Unlock for Editing" (F2) on an HTML page (index.html for
example).

2. I want to refresh the page on the browser but the change remain there.

Same thing I want to do for JS files, etc.

I know that this can be done indirectly but this takes lots of time (I have to
debug many websites):

1. I save the "Response Body" in a local page (index_local.html)

2. I edit it locally

3. I go to "AutoResponder"

4. I "Add Rule"

5. I go to the combo for the "Find a File"...

6. I browse, I select, and so on...

This takes some time and brain power which I would like to preserve for the
actual debugging.

May I ask if there is a FAST alternative that I miss in the options?

Thank you all.

Hi, I'm trying to log traffic from multiple users on a single Citrix server and then review each user's traffic separately. I have Fiddler running and have a special published app they can select that will set their proxy settings before launching the web application in IE - but I can't figure out how to uniquly identify all traffic from a single user when reviewing a multi-user log file. Is there something that uniquely identifies the browser session? or a way to have Fiddler listen on multiple ports (so I could send one user to each port and filter on that?

Hi there and thanks for this great tool!

Is it possible to highlight incoming/outgoing sessions other than using bold?
For example, I would like all requests with "error.gif" in them to have a yellow background color so I can easily spot them when they pop up.

Ideally, I would like to simply right-click a session, mark it with a color and have all future similar sessions be highlighted with the same color.

Kindly,
Stian

if (oSession.HostnameIs("www.google.co.uk") && oSession.uriContains("query")){
oSession["ui-color"]="orange";
oSession["ui-bold"]="true";
  oSession.oRequest.FailSession(404, "Blocked", "Fiddler blocked  file");}

The above script blocks only  www.google.co.uk, It does'nt work if there it's a different country code domain

for example 
www.google.co.br
www.google.co.cm

I tried using wildcards *.google.*, but it does not work. Any ideas?

Thank you
