with proxy_connect i cannot intercept errors with error_page

[hbvenancio]

Hi,
first of all congratulations for the module!

I have built and installed it successfully (on linux). It works fine as a forward-proxy but it seems i cannot proxy_intecept_errors.
I am able to "intercept" the requests passing through nginx but not the responses and rewriting them. In the below example i am trying to intercept the 401 HTTP code and rewrite it to 302, but seems i am not able to intercept errors ?

server \{
    listen 8755;
    proxy_connect;
    location / \{
      proxy_pass https://intrauat.web.bc;

      proxy_intercept_errors on;
      error_page 401 = @rewrite_401;
    }

    location @rewrite_401 \{
      return 302 https://intrauat.web.bc/login;
    }
 }

I am not sure whether this is by-design, a bug, or even a feature not yet implemented.

Could you please help me understanding ?

Many thanks in advance.
BR,
Hugo

hi @hbvenancio

The proxy_connect module works instead of proxy module (e.g. proxy_pass directive), this module only proxied backend raw stream to client. However, proxy_intercept_erros only works for proxy module.

For more details and why this module cannot intercept the proxied backend raw stream, see:

• What functions does this module implement: What functions does this module implement? #78
• difference between proxy_connect module with proxy module: What's the difference between proxy_pass and proxy_connect_address? #84 (comment)

Hi, I understand this is not yet implemented but don't you think it would be a good idea? Br Hugo

Not easy to implemented, see my comment #108 (comment).

This module is designed to proxy raw stream directly without parsing and modification.
