In order to use our available bandwith more efficiently, we installed mod_gzip
as Apache module a while ago. The mod_gzip
module allows certain HTTP traffic to be compressed at server-side and decompressed again at client-side, all on-the-fly.
I have been testing this feature for a while now and tests have always been inconclusive as to whether the traffic was actually getting compressed or not. Not all browsers support compression - or rather content-encoding
- but even when using the same browser all the time it gave me erratic results. HTTP 1.1
support is required for content-encoding.
Until detailed tracing gave me some valuable hints. Most proxy servers block/do not pass HTTP 1.1. content-encoding
in which case all pages get transferred uncompressed. However MSIE 4+ has the option to explicitly enable HTTP 1.1 compliant traffic over proxies.
So if you are using a proxy server to connect baanboard and you would like to see a speed increase in load times, then make sure you have the following options enabled:
Tools > Internet Options > Advanced > HTTP 1.1. settings > (see picture)
This should work with all version of MSIE 4+ and Opera.
If you want to test if mod_gzip
is working for you in MSIE than you can check the forum home (http://www.baanboard.com
) page size through the File > Properties
menu. If the size is around 70K then it's uncompressed, if the page size is 7K then mod_gzip
is saving bandwith for you
Try and let me know your experiences!
