Disabling Expires headers

[Matt Raible]

Is it possible to turn off wro4j setting expires headers. I'm using Apache to gzip and set expires headers on my JS and CSS. However, when I configure wro4j to concat/minify my assets, it overrides Apache's expires headers. It seems to be setting them the expiry date to 2000/1/1.

Thanks,

Matt

Hi Matt, 

The expected default behavior is to have expire headers to be set 1 year in the future. It is weird that your expiry date is set to year 2000 (would be curious to understand why). Nevertheless, in order to control the expire date headers, you have the following options:

1) Extend WroFilter and override the  WroFilter#setResponseHeaders(final HttpServletResponse response)  method.

2) Extend WroFilter and override the  WroFilter#newResponseHeadersConfigurer()  method. This method returns ResponseHeadersConfigurer object which 

3) Create another filter which is mapped to the same path as WroFilter and override the headers in doFilter method.

4) Add in wro.properties a new property with key header. 

Example: header=Expires: Thu, 15 Apr 2010 20:00:00 GMT | cache-control: public

Let me know if that helps or if you have other suggestions.

Thanks,

Alex

I figured out what was causing this. I had the following in my wro.properties:

debug=true

Changing it to "false" gives me the behavior I want.

Thanks,

Matt

Indeed, the caching is disabled in development mode (debug=true), to prevent browser caching.
