Heroku: enable gzip compression

Add to your .htaccess file:

SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application/x-javascript application/x-httpd-phpBrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip

Codeship - heroku continous deployment: Push failed: could not store slug!

Trying to deploy automatically form codeship to heroku I was getting the error:

-----> Compressing... done, 72.0MB
-----> Launching...!     
Push failed: could not store slug!     
If the problem persists, see http://help.heroku.com and provide Request ID 

I solved the issue by adding the heroku url project and enable the "force push" flag in the option: Project settings > Deployment > Heroku Deployment > more options.
