My current Splunk regex query

10.66.189.62 -- -- -[17/May/2022:05:59:16--0400]--502- "POST /astra/sliceHTTP/1.1" req_len=1776-req_cont_len=117-req_cont_enc="-"-res_body_len=341 res_len=733 "https://ninepoint.blackrock.com/astra/". "Mozilla/5.0- (Macintosh; Intel-Mac-OS-X-10_15_7) -AppleWebKit/537.36-(KHTML,-Like-Gecko)
Chrome/10.0.4896.127 Safari/537.36" x_fw_for="-".req_time=278.326-ups_res_time=278.326 ups_con_time=0.011-ups_status=502-pipe=. -VNDRegID=undefined-

gives me;

POST /astra/sliceHTTP/1.1

 

I want to apply another query on the result of above query to get  POST/astra/sliceHTTP/1.1     ,i.e

/astra

Is there a way or a better regex pattern which can provide me the following?

What is your current regex?

Are you wanting to do this at indexing or search time?

Will the string always start with POST?

My current regex is 

rex field=_raw \"\w*\s(?<url>.*?)\s.*\"

 

And it could start with POST or GET 

 

Thank you
