Woa.
I can not generate it because website has some special content that I can not get.
My request is to save request data when I submit anything.
Is there any solution?
In Inspection mode, Can you save that content.
@BasUser110 a mask is not a data type, but a url mask. The url does not have to contain a file extension. You need to look at which queries load this data and write a mask for them.
Open developer tools in your own browser and look at the network tab. Click on the requests and click Block Request then refresh (Right click refresh button and reload without cache)
Keep blocking images and scripts until the website stops working
Take that list of blocked stuff and put it in your script using Request Mask Deny
