about: URI scheme

無意間發現這玩意，真是太有趣了~~

wiki的定義如下:
about: is an internal URI scheme (also known as a "URL scheme" or, erroneously, "protocol") in various web browsers to display certain built-in functions. It is not an officially registered scheme, and has no standard syntax.

像我用firefox，在address bar輸入
about:config 可以看到firefox 所有的設定參數
about:plugins 可以秀出firefox目前裝的plugin
about:cache?device=memory
about:cache?device=disk
上面這兩行很好用，可以很方便把cache裡的東西存出來，尤其像是swf檔這種無法按右鍵另存的。

方法如下:(轉載自http://labnol.blogspot.com/2005/11/save-flash-from-firefox-and-ie.html)

1. Saving Flash files from Firefox

Firefox for Newbies
a. Click Tools - Page Info
b. Click the Media Tab on the Page Info Windows
c. The media tab has a complete list (with preview) of Images, CSS Files and Shockwave Flash files that were downloaded by the Firefox browser while rendering (loading) the page.
d. Scroll down the list and locate the swf file.
e. Click the "Save As" button. Select some directory on your hard drive and save the file (No need for a third-party plug-in)

Firefox for Geeks and Power Users
a. Type about:blank in the Firefox address bar
b. Now click List cache entries or directly type about:cache?device=disk (Disk cache device)
c. Press Ctrl+F and try to location the flash file by typing some part of website URL or the flash file name or just .swf. After some hit and trial, you should be able to locate the swf file URL
d. Click the SWF URL to open the Cache Entry Information page. Right click on the link and choose "Save link as"
