Then, we don’t mind First and Second ways.
Just focus on third way.
59. Press short key[Alt+Q] that quick executor on main display panel.

61. How is it going ? Does packets are stopped by break point well?
Now, Manipulate some request Data.

2. I don’t need to capture packets.
3. I want to compare A Host and B Host packets.
4. I want to know the web page’s resource weight
85. 2. I don’t need to capture packets.
There are three way to stop fiddler’s packet capturing
- Click F12
- Check File-> Capture Traffic
- Click Status ‘of Capturing’ On Left of bottom
86.
87. 3. I want to compare A Host and B Host packets.
Select two packet that want to compare.
Then, right click and choose ‘Compare’. Or press ‘[Ctrl+w]’
88. Fiddler has default option that comparing packet need a tool. That’s name ‘WinMerge’.
But, we didn’t have it. then, we have to install it.
(If you install ‘WinMerge’, I recommend you default setting(just click ‘next’ on and on). It hasn’t special)
** Actually, ‘WinMerge’ tool is simple, feather and free, I like it
