Servlet
|
Description
|
AdminServlet
|
Implements iServer Administrator.
Normally defined as a Servlet aliased as /admin.html.
|
CgiServlet
|
This Servlet implements CGI.
bindir
|
The base directory which contains CGI scripts.
Normally ./cgi-bin.
|
exec
|
The shell to use.
Normally c:\\command.com /c for WIN32 and
/bin/sh for UNIX.
|
Normally defined as a Servlet aliased as /cgi-bin.
|
ClusterRedirector
|
The Cluster Redirector provides load balancing and fault
tolerance by redirecting client requests to an available
workgroup of servers.
hosts
|
The comma delimited list of the names of the servers
in the workgroup that requests will be redirected to.
For example:
p2,p3:8080
|
interval
|
Used to specify in milliseconds how often the
workgroup servers status is updated.
A value greater than or equal to 50 milliseconds.
If an interval is not specified or if (0) zero is
used then the workgroup server status is only checked
if the method is best when the request is made is
made.
1000 milliseconds is a good value to use.
A value too small may have a negative impact on
performance and a value too large when method is best
may saturate a workgroup server with requests.
|
method
|
The method used to determine which server within
the workgroup will service the current request.
best - the server with the best response time.
next - the next available server.
If a method is not specified then next is used.
|
Normally defined as a Servlet associated to the base URL to
redirect.
|
FileServlet
|
This Servlet provides access to both files directories.
Parameters for File are defined in iServer Administrator ->
Manager -> Server
Default File
|
The name of the default html document to retrieve, if non was specified.
index.html is the default for iServer.
|
File Cache Size
|
The amount of memory in megabytes to use as a file
cache.
8 is the default for iServer.
Must be 1 or more megabytes in size. Use 0 to disable
the cache.
A file cache may improve performance.
|
Directory Access
|
Whether to allow directories to be displayed.
No is the default for iServer.
Setting this value to Yes is potentially a security
hole.

The root directory for html files and documents.
./wwwroot is the default for iServer.
./public_html is also a popular value used by

iScriptServlet
|
Provides interface to iScript.
basedir
|
The base directory which contains iScript scripts.

iScript is available as a separate download.
|
SSIncludeServlet
|
Provides support for SSI.
exec

The shell to use when executing #exec
directive.
Normally c:\\command.com /c for WIN32 and
/bin/sh for UNIX.
