How to prevent http file caching in Apache httpd MAMP

Question

I am developing a single page Javascript application in MAMP  My JavaScript and HTML template files are getting cached between requests   Is there a simple way to indicate in MAMP that I want to prevent http file caching  Possibly with a  htaccess file  Where do I place the  htaccess or modify the virtual host for MAMP on Mac

Tried this  Should work in both  htaccess  httpd conf and in a VirtualHost  usually placed in httpd-vhosts conf if you have included it from your httpd conf   lt filesMatch  quot    html htm js css   quot  gt    FileETag None    lt ifModule mod headers c gt       Header unset ETag      Header set Cache-Control  quot max-age 0  no-cache  no-store  must-revalidate quot       Header set Pragma  quot no-cache quot       Header set Expires  quot Wed  11 Jan 1984 05 00 00 GMT quot     lt  ifModule gt   lt  filesMatch gt    100  Prevent Files from being cached This is similar to how google ads employ the header Cache-Control  private  x-gzip-ok  quot  quot   gt  to prevent caching of ads by proxies and clients   From http   www askapache com htaccess using-http-headers-with-htaccess html And optionally add the extension for the template files you are retrieving if you are using an extension other than  html for those

Based on the example here  http   drupal org node 550488  The following will probably work in  htaccess    lt IfModule mod expires c gt       Enable expirations     ExpiresActive On       Cache all files for 2 weeks after access  A      ExpiresDefault A1209600     lt FilesMatch    js   html   gt       ExpiresActive Off    lt  FilesMatch gt    lt  IfModule gt

Without mod expires it will be harder to set expiration headers on your files  For anything generated you can certainly set some default headers on the answer  doing the job of mod expires like that    lt  php header  Expires    gmdate  D  d M Y H i s  G M T   time     3600      gt     taken from  Stack Overflow answer from  brianegge  where the mod expires solution is also explained   Now this won t work for static files  like your javascript files  As for static files there is only apache  without any expiration module  between the browser and the source file  To prevent caching of javascript files  which is done on your browser  you can use a random token at the end of the js url  something like  rd 45642111  so the url looks like    lt script type  texte javascript  src  my url myjs js rd 4221159546  gt    If this url on the page is generated by a PHP file you can simply add the random part with PHP  This way of randomizing url by simply appending random query string parameters is the base thing up  n no-cache setting of ajax jQuery request for example  The browser will never consider 2 url having different query strings to be the same  and will never use the cached version   EDIT  Note that you should alos test mod headers  If you have mod headers you can maybe set the Expires headers directly with the Header keyword

I had the same issue  but I found a good solution here  Stop caching for PHP 5 5 3 in MAMP  Basically find the php ini file and comment out the OPCache lines   I hope this alternative answer helps others else out as well
