All of the work performed by this recipe is accomplished inside of the
checkLink
method. This method begins by creating a
SpiderOptions
object named
options
.
Then a
MemoryWorkloadManager
is specified. A
MemoryWorkloadManager
will work with relatively large sites; however, if you are going to check an extremely large
site, you may want to use an
SQLWorkloadManager
.
