Authcache support

[davidwhthomas]

Authcache provides a standalone implementation of index.php for a partial bootstrap and rapid response. However, this nginx conf prevents that file from being parsed by PHP and returns a 404 instead.

The file name is:

authcache.php

Example request URL:

http://www.example.com/sites/all/modules/contrib/authcache/modules/authcache_p13n/frontcontroller/authcache.php?a=authcache_admin_config&r=frag/form-token&o[q]=

I tried this in drupal.conf without success

location ~* ^.+/authcache\.php {

  ## FCGI backend like php-cgi or php-fpm.
  include apps/drupal/fastcgi_drupal.conf;
  fastcgi_pass phpcgi;        

}

How do you recommend adding to the nginx conf so this PHP file can be correctly requested and processed?

Thanks for the great nginx conf.

OK, I think I may have found a solution.

I added to drupal.conf, near the end

## Authcache Support.
location ~* ^.+/authcache\.php {
  ## FCGI backend like php-cgi or php-fpm.
  ## Configured for Authcache.
  include apps/drupal/fastcgi_drupal_authcache.conf;
  fastcgi_pass phpcgi;        
}

## Any other attempt to access PHP files returns a 404.
location ~* ^.+\.php$ {
    return 404;
}

Then I copied fastcgi_drupal.conf to fastcgi_drupal_authcache.conf and tweaked it as such (diff output):

9c9
< fastcgi_param SCRIPT_NAME /index.php;
---
> fastcgi_param SCRIPT_NAME /authcache.php;
25c25
< fastcgi_param SCRIPT_FILENAME $document_root/index.php;
---
> fastcgi_param SCRIPT_FILENAME $document_root/sites/all/modules/contrib/authcache/modules/authcache_p13n/frontcontroller/authcache.php;

After that the requests returned a form token, as expected.

Cheers, David

I am experiencing same issues; however, applying these changes did not fix my problem. This does not address the issues when authcache.php is used to build the "frag" elements via ajax/esi on authecache module.

davidwhthomas, was there something more you did to get this configuration working?

Thanks a lot for this!

[davidwhthomas]

@cthshabel adding the handler for authcache.php as above (calling fastcgi_drupal_authcache.conf) was all I needed to change for authcache to work. Currently authcache reports ESI is working from the admin test page. Hopefully you can resolve your issue there too.

[steventhabel]

@davidwhthomas thanks for the quick response. And also for writing this up in general. I was very lost diving into authcache, but this is definitely the problem. I temporarily allowed all .php scripts through and sure enough it worked. SO authcache.php not getting through nginx is the problem somewhere.

[davidwhthomas]

@cthshabel make sure the authcache.php path is correct in fastcgi_drupal_authcache.conf here:

fastcgi_param SCRIPT_FILENAME $document_root/sites/all/modules/contrib/authcache/modules/authcache_p13n/frontcontroller/authcache.php;

e.g: perhaps you're not using the "contrib" subfolder or have authcache.php in a different folder there.

Note, I'm using this with PHP-FPM as the fastcgi handler.

I hope that helps.

[steventhabel]

@davidwhthomas you are a saint! my directory was not using "contrib" subfolder. that is what i get for going in and copying line for line. in fear of getting the path wrong, i didn't even pay attention to what yours was.

either way, i changed it to make sure it was mine. restarted nginx. restarted php5-fpm. still no luck :/

included in settings.php --- $conf['authcache_p13n_frontcontroller_path'] = 'authcache.php'; copied authcache.php to drupal root

stumped.

[steventhabel]

@davidwhthomas maybe i am mistaken because it did clear up some errors. but still 404 (Not Found) for these type of url:

https://www.example.com/authcache.php?a=search_box&r=frag/form-token&o[q]=&v=hts7k4 https://www.example.com/authcache.php?a=&r=frag/menu-local-tabs&o[q]=node/61&v=hts7k4 https://www.example.com/authcache.php?a[nh][u][0]=61&r=setting/node-history&o[q]=&v=hts7k4

[davidwhthomas]

Yes, /authcache.php will 404 as the nginx conf is set to the original location in the module folder i.e:

fastcgi_param SCRIPT_FILENAME $document_root/sites/all/modules/authcache/modules/authcache_p13n/frontcontroller/authcache.php;

Sounds like progress though, good luck with the rest of the conf tweaking - getting there.

[steventhabel]

@davidwhthomas definitely will get there :) thanks a lot for your help! means a lot
