Conflict with multiple currency plugin about srcache-nginx-module HOT 8 CLOSED

Your website varies the response using the request IP.
That setup doesn't go well with a cache in the proxy.
The right way to do this is to map the request IP to a request Header before srcache handles the request, and Vary the response upon that header.

• Request:
  IP: a.b.c.d
  host: domain.com
  Accept: text/html
• Geolocation nginx plugin (using e.g. ngx_http_geoip_module)
  IP: a.b.c.d
  host: domain.com
  Accept: text/html
  X-ClientCountry: France
• Srcache:
  Here you should build the request key using X-ClientCountry header
• Application:
  response.append('X-ClientCountry', 'Actual detected country')
  response.append('Vary', 'X-ClientCountry')
• Srcache:
  Build store key using response X-ClientCountry header

from srcache-nginx-module.

I wrote Actual detected country because the Country detected by geoip might not be the one you actually choose in the application. For example you might map 'FR' and 'ES' to 'EU' in the application, so you have to tell the cache (as done above) to set its store key accordingly.

Thank you for replying, I understand that solution but I don't know how to build store key using response X-ClientCountry header.

Could you give more information?

from srcache-nginx-module.

It's great if you give me an example

from srcache-nginx-module.

From the documentation example (assuming you're using X-Client-Country header)

  more_set_headers 'X-Country-Code: $geoip_city_country_code3';
  set $fetchKey "$geoip_city_country_code3-$uri?$args";
  set $storeKey "$sent_http_x_client_country-$uri?$args";
  srcache_fetch GET /memc $fetchKey;
  srcache_store PUT /memc $storeKey;

Cool huh ?!?

set $key "example.com_page:https$http_cf_ipcountry$request_method$host$request_uri";

I'm using Cloudflare so that's my config and it's worked =))))

Thank you so much :D

from srcache-nginx-module.

Cool ! If you're using Cloudflare then yes, there is already a http header available, so indeed there is no need to set one up.

Oh, I forgot it
too much focus on coding =))
