Hi,

I have a case that after a response from upstream server, I want to generate one subrequest via ngx.location.capture to talk to another internal server, but it's not supported as the document says:
"
header_filter_by_lua
For now, the following Nginx Lua APIs are disabled in this context:
...
• Subrequest APIs (e.g., ngx.location.capture and ngx.location.capture_multi)
...
"

I am wondering how much efforts needed to support this or is there any workaround?

Thanks,
Jun
