How to GZip dictionaries?

Avatar

Level 2

As we GZip CSS and JS files in AEM, we would like to GZip dictionaries (dict.en_US.json, dict.fr_US.json, etc) as well. How can we achieve that? Help would be greatly appreciated.

Thanks,

Mohan

Hi,

What you mean with "gzip", is the compression of the HTTP body; it is offered by the clientlibrary manager ootb for clientlibs, but AFAIK AEM is not using it for other files.

But your webserver (which also hosts the dispatcher) can do the compression on-the-fly as well, if you instruct it to do so (for example you should use mod_deflate for Apache HTTPD). This doesn't have negative impact on the performance of the site, but then also cached files benefit from this kind of compression.

But please note: Any HTTP client does this compression/uncompression transparently. So the files in the dispatcher cache are not compressed then.

Mohan,

Can you explain whats the use case here. Unlike CSS,JS which are used in the client browser the dictionaries are  consumed in the server side. The dictionaries keys referred in JSP/HTL (Sightly) get the value from the dictionary in the server side itself.

Hi Jörg, thanks for the reply. Yeah, gzip I mean compression only. AEM doesn't compress files other than CSS, JS. Will try with webserver.

Vijayraj, we are using dictionaries' keys in javascript using Granite library. In this case dictionary json is generated. We are looking to compress these jsons.
