Get header value using Lua before hiding header by clear_more_headers

[SanaZulfiqar73]

Hi,

I have the scenario where I am receiving a response header in nginx and want to retrieve one value from the response header using lua in the http block.
Also, When I send this response header to user I want to remove that header from the response. When I do that using "clear_more_headers" in server block, Lua block also don't get the value for that response header.
I want to know is there a way I can get the value first and then clear that header.

thanks
