Hello guys,

i'm using KDP - Dynamic Player....in my swfobject directory url, i found parameter cache_st

http://www.kaltura.com/kwidget/cache_st/1248278524/wid/.........

so, i want to ask some question :
- what is the mean of cache_st?
- what is the function of cache_st?
- what is the mean of number 1248278524 after the parameter cache_st in the url?
- where can i get a documentation about this parameter?

thanks for your advise.

edi. ^^

I believe it's there just to tie the uiConf and widgetID so you can't dynamically mix and match. For security purposes. That's my guess. :-) That's why you can't swap out uiConf willy nilly.

I have the same question. What is cache_st parameter in KDP url?
I don't think it ties to the uiConf as I can see all different cache_st in my KMC video embed code which is generated by Kaltura system.

I am guessing cache_st is for "cache static". The number is the number of seconds since Jan 01, 1970. 1301354732 as I type (March 2011).

You may omit this parameter (but it seems to slow things down sometimes if you do, at least on one test server here; I suspect it ought not to).

I've also played with faking it (eg setting it to something like strtotime('monday') in order to recycle the same folder for a week ... this seems to work, but I'm just experimenting - don't blame me :D

Thanks grobot. That helps. :)

I used to have the problem of the KDP caches the remix video. KDP won't play the last version of edited remix right after the editing. It plays the previous version instead.
Updating cache_st solves this problem.
