Redirect based on response headers

mszary

Hi Guys.
Seems like it's impossible to use ngx.redirect inside header_filter_by_lua directive.
How would you approach redirection based on the response header (ie. Content-type) ?

I'd like to detect if the response is in JSON format and then ignore the content and redirect to predefined path.

Any ideas :) ?

Hi!

I think a transigent approach may can help you, you can use the error_page directive, like error_page 789 = @xxx

In your header_filter hook, check the condition and if you want to launch the redirect, you can use the ngx.exit(789) and let an internal redirect happens.

Then in your new location, you can do whatever you want.

Beautiful :) Works like a charm. Thank you.
