[OT] Gzip compression of script files
Hi,
I have javascript/css files and looking at GZipping them and sending it
to the browser. I am aware that i can do a GZip compression during
runtime using a filters, by writing the content to GZipOutputStream. I
am just wondering if it is possible to GZip these files during build
time and then simply serve them during a request(run time) from the
filter. I haven't seen any such example. Possibly i am missing some thing.
Can anyone let me know, if it is achievable? If not why? Any pointers
would be great.
Cheers,
Vijay.

Hi Mike,
Thanks for letting me know about this. I will take care to test it on
slow machines.

I had problems on IE where compression of gzip didn't works.
On the first page load, we had javascript error.
On the second page load, it works because the ungzipped file was in cache.
If we clear browser cache, we have the error again ...
It seems to happened It happend on slow machines.
so, be careful with it. I personally never gzip .js.

Sebastin,
Thanks for all the information and pointers. Hmm i didn't realize that
i meddled with another thread. Group i am very sorry for the mistake. I
just accomplished what i wanted, it was more of a bug that is why i
didn't get it to work.
I do understand that i can get it done this done at container / web
server config level or at the code level. Nice link if others are think
in these terms. http://www.seifi.org/?p=482
Thanks,
Vijay

Hello,
First of all: You should open a new thread for new questions. Answering to
existing threads might conceal your message for most people.
Anyway:
Compressing javascript, css and other files is possible if the browser
supports this.
The simplest solution for this is to install a webserver (i.e. apache)
additional
to your application server so that a request goes through the web
server. This webserver
can be configured to compress content, probably also HTML files or other
content;
look for 'mod_deflate'.
If everything is right you should then have a transparent compression
for selected
filetypes w/o needing to compress anything "manually".
An other approach is to use a javascript "compressor" like
http://compressor.ebiene.de/ which converts/eliminates white spaces and
word wrapping.
