Disk Cache

@@ +1 @@
+Konqueror
+
+Cache is stored in "~/.kde/cache-katherline/http/[0-9a-z]/"
+
+The top level directories are the first letter in the host and is historical when processing a lot of files in one dir was harder.
+
+Each file is stored by itself.  So the file http://www.reddit.com/static/aupmod.png goes in: r/www.reddit.com_static_aupmod.png_2cd5ba49 
+Each file: "host"_"file"_"fullUrlHash"
+
+Each file contains the following (minus the text before each : so the first line is just '7') 
+{{{
+Version: 7
+url: http://www.reddit.com/static/aupmod.png
+Creation date: 1213180806
+Expire date: 1213765446
+ETag: 1207334405.0-334
+Last Modified: Fri, 04 Apr 2008 18:40:05 GMT
+File: <all contents>
+}}}
+
+In KDE 4 the file is gzip'd for 90% savings
+Also r/www.reddit.com_static_aupmod.png_2cd5ba49_freq contains the number of times the url has been requested in a fashion that is not lock safe a has a bunch of problems.  Not something I would recomend copying
+
+A seperate application goes through cleaning the cache.
+
+A very simple system.
