Gzipping dynamically generated responses

[jonspalmer]

I have a number of RESTful controllers that return xml content. Ideally I’d like to gzip the xml results. What is the easiest way to achieve this in Grails. The zipped resources plugin does a nice job of gzipping static resources but my problem is that the xml is dynamic. I’d like something like this to work:

 

http://myapp.com/api/some/resource.xml.gz

 

Thanks

Jon

Hi Jon,

Just look at the source for the zipped-resources mapper and rip it off for a normal controller/filter. It should be easy there's almost no code in the zip mapper:

https://github.com/Grailsrocks/grails-zipped-resources/blob/master/grails-app/resourceMappers/org/grails/plugin/zippedresources/ZipResourceMapper.groovy

Note that the mapper does not set the extension to .gz as apparently that causes problems with some IE versions of the past. You could/should do the same I think, and just set the right response header for Content-Encoding.

Is .zip OK? 

http://grails.org/plugin/grails-ant

Note that I don't think that works with Grails 2.x. It's on my todo to update.

I'd recommend putting this in the apache instance you use to front your grails instance.

Or just put a servlet filter around your application.  There must be dozens of blog posts out there that describe how to install a gzipping servlet filter into a webapp.

Yup, I hadn’t realized how simple it is to have Apache take care of that. For static content its nicely efficient for the resources plugin to do the gzipping once, for dynamic content Apache is a great way to do it.
