Apache config

Make sure you have the following modules enabled in Apache for this configuration to work properly:

• mod_rewrite for URL rewriting.

From your drupal folder .htaccess file  (usually the web folder) paste subsequent boost block immediately after:

  # uncomment the following line:
  # RewriteBase /

Paste this right after (Boost 8.x-1.x-dev)

  # ---- BEGIN BOOST ----

  RewriteCond %{REQUEST_METHOD} ^(GET|HEAD)$ [NC]
  RewriteCond %{QUERY_STRING} ^$
  RewriteCond %{HTTP_COOKIE} !(SESS|SSESS) [NC]
  RewriteCond %{DOCUMENT_ROOT}/sites/default/files/boost%{REQUEST_URI}.html -f
  RewriteRule ^ sites/default/files/boost%{REQUEST_URI}.html [L,E=BOOST_CACHE:1]
  #  # IMPORTANT: allow Basic Auth testing (do NOT bypass on Authorization)
  #  # So: do NOT add any Authorization-based skip.

  <IfModule mod_headers.c>
    Header set X-Boost-Cache "full" env=BOOST_CACHE
    Header set X-Boost-Cache "full" env=REDIRECT_BOOST_CACHE
  </IfModule>

  # ---- END BOOST ----
