Hi, How to set the origin server status as a custom header?
I tried the header rewrite plugin with ATS 6.2.0 with the following configs.
plugin.config
```
header_rewrite.so header_rewrite.config
```
header_rewrite.config
```
cond %{SEND_RESPONSE_HDR_HOOK}
set-header X-Origin-Status %{STATUS}
```
However I got the following response header.
X-Origin-Status: 0
I expected the value is 200, not 0.
Thanks,
