Hi at all !
I'm studying Fiddler and I'm trying to know what can I do with it.
My questions are :

1. Can I change "User-Agent" value when I receive a particular packet ?
2. Can I change "Request URI" value when I receive a particular packet ?
3. In general case, Can I change every field value when I receive a particular packet ?

Problems using regular expression with capturing and non-capturing groups

I was having problems to replace some strings in the response. To look for the pattern I have using a regular expression, but I only want to replace one part of the expression. I was trying to define capturing groups with () and non- capturing groups with (?:). I have tested in some webs about regular expression and it works, but in fiddler doesn´t.

For example. I have this code:

var oRegEX=/(?:(value="))(NOIA)/gi;
oBody = oBody.replace(oRegEX, "xxxxxx");

I look for expressions like value="NOIA" but I only want to replace the word NOIA like this value="xxxxxx"

It has to be replaced the string NOIA but it replaces all value the string .

Could you help me??

Controlling which protocols Fiddler will accept for inbound connections

Hello,

I understand that by default Fiddler 4 will accept inbound connections using any HTTPS protocol version.

Is there a way to control which protocols Fiddler will accept for inbound connections? for example, allowing only SSL3 and TLS1.0.

Thanks

Permission to incorporate fiddler in third-party products

Hello to everybody on this forum. We are a Russian-based software company.

One of our products is a Windows-based security gateway that implements a web proxy as its integral part. So far, our web proxy only supports HTTPS via the HTTP CONNECT tunneling method. We have come across Fiddler while researching the possibility of decrypting HTTPS (SSL/TLS) in our program. Which brings me to my questions.

1. Does Fiddler (HTTPS decrypting functionality) exist as a DLL for a Windows OS?
2. Is there an API that Fiddler (HTTPS decrypting functionality) provides to other software?
2. Can we obtain such a DLL and API specifications from you?
3. Are we free to incorporate that DLL in our software?

Thank you in advance.

Fiddler not capturing IE requests only for intranet

Fiddler is capturing all internet requests from internet explorer, but as soon as I request something internally (site hosted in iis on my pc or site hosted in iis on server in our domain), fiddler does not show anything.

When I use chrome, all traffic shows up (intranet and internet), no problem there.

But I need fiddler for some internet explorer specific problem, so does anyone have any idea why fiddler is not capturing requests from IE for intranet sites?

Google Search hijacked only when not being observed. With Fiddler Capture normal results are returned.

It looks like something is using the FiddlerRoot certificate as a means to hijack google. I posted about it on superuser at the below link. I'd really like to not have to reinstall Windows.

How to setup fiddler to capture HTTPS traffic

I was able to load a HTTPS site in chrome. But as soon as i start fiddler to capture the HTTPS, I can't load that site anymore. I get this in my chrome.

Your connection is not private Attackers might be trying to steal your information from testsite.com (for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID

My question is how can I use fiddler to capture HTTPS traffic?
