This a national stock exchange website through which i have to refresh data after 1 min to get updated data & trade accordingly. But the issue is COOKIE gets expired after a certain time & I have to set it again & again. Is there any way to get Cookie header value from Nse website & then I can easily pass it as a value to this query to set cookie after a set time interval. Thanks in advance!!
