	Brief Description of the WWW Server Benchmark
	---------------------------------------------

Multiclient Infrastructure
--------------------------
Same as LADDIS


Workload
--------
The workload is specified with two files:
- mixfile
  specifies request type distribution
- urlfile
  specifies URLs for each operation with probability of access

An example mix file:
get 50
head 25
post 25

An example url file:
GET http://cnet18/file1.html 0.5
GET http://cnet18/file2.html 0.5
HEAD http://cnet18/file1.html 0.5
HEAD http://cnet18/file2.html 0.5
POST http://cnet18/cgi-bin/script1.sh 0.5
POST http://cnet18/cgi-bin/script2.sh 0.5
