Hi Sachin,
I would do it like this:
stick-table type string size 1M expire 10m store conn_cur
tcp-request inspect-delay 5s
tcp-request accept if HTTP
acl is_range hdr_sub(Range) bytes=
acl is_path_throttled path_beg /public-api/v1/fs-content-download
http-request set-header X-track %[url]
http-request track-sc1 req.hdr(X-track) if is_range is_path_throttled
http-request deny if { sc1_conn_cur gt 2 } is_range is_path_throttled
There might be some typo, but you get the idea.
