Filter Fiddler traffic

Question

Is it possible to instruct Fiddler to only show me traffic directed to a specific host name? In other words, can Fiddler traffic be filtered for Host?

Answer 1

Go to fiddler script tag and paste following into OnBeforeRequest function. (Screenshot below)

if (oSession.url.Contains("ruby:8080") || oSession.url.Contains("localhost:1234")) 
{   
     oSession["ui-hide"] = "yup"; // "The "yup" value is unimportant"
}

This way you can filter by any part of url be it port, hostname or whatever. It is useful for filtering out localhost trash as filtering by host alone does not do this...

EDIT as per @baburao comment: Apparently fiddler gives access to process info through the x-ProcessInfo flag. So if you wanna hide a process (say for 'chrome'), change the condition to: if (oSession["x-ProcessInfo"].Contains("chrome"))

Hope this saves you some time.
