Incorrect RewriteConds and RewriteRules generated and shown on install page

[jamieburchell]

The install page shows these rules:

RewriteCond "%{DOCUMENT_ROOT}/var/www/shared/web/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html" -f
RewriteRule .* "/var/www/shared/web/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html" [L]
...
RewriteCond "%{DOCUMENT_ROOT}/var/www/shared/web/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.xml" -f
RewriteRule .* "/var/www/shared/web/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.xml" [L]

Note RewriteCond "%{DOCUMENT_ROOT}/var/... and RewriteRule .* "/var... which are incorrect because it's adding the full path again after %{DOCUMENT_ROOT} making it /var/www/var/. The directives should have been:

RewriteCond "%{DOCUMENT_ROOT}/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html" -f
RewriteRule .* "/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html" [L]
...
RewriteCond "%{DOCUMENT_ROOT}/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.xml" -f
RewriteRule .* "/app/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SLASH}%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.xml" [L]
