apache - what's the rewrite rule meaning? -

- 

rewriteengine on      rewriterule ^(.*)$ http://$1 [r=301,l]

what's meaning of line ( rewriterule ^(.*)$ http://$1 [r=301,l] ). thank you.

it's 301 (permanent) redirect whatever path on relative domain name:

http://<your website>.com/example.com redirect http://example.com.

rewriterule ^(.*)$ http://$1 [r=301,l]

it literally saying, "ok, found in folder should considered permanently redirected domain".

  • ^(.*)$ means select , call $1
  • http://$1 means go domain stored in $1
  • r=301 refers status code 301, "permanently moved" redirect.
  • l means final instruction matching pattern. no other redirect rule after 1 effect these redirects.

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
