HTTP Config

Clients can access EAServer and retrieve HTML pages using a Web browser. You can customize certain aspects of your server’s HTTP behavior by modifying the HTTP configuration properties listed in Table 3-3.

**Table 3-3: HTTP properties**
Property	Description	Default value	Comments/example
Domain Name	Domain name in .company.xxx format. Set this only if you are configuring the redirection URL for use with a Web proxy.	N/A	See “Configuring redirection addresses when using a proxy server”.
Proxy HTTP Port	When a Domain Name is specified, the HTTP port used in redirection URLs.	80	See “Configuring redirection addresses when using a proxy server”.
Proxy HTTPS Port	When a Domain Name is specified, the HTTPS port used in redirection URLs.	443	See “Configuring redirection addresses when using a proxy server”.
Proxy Protocol	When a Domain Name is specified, the protocol for redirection URLs.	The protocol of the original request	See “Configuring redirection addresses when using a proxy server”.
Document Root	The path to the directory where documents are served.	$JAGUAR/html (UNIX) %JAGUAR%\html (Windows)	/work/WWW/ C:\work\WWW\
Default Web Application	The default Web application.	None	The Web application must be installed in the server. When specified, clients’ requests are redirected to the Web application context. For example, if the default Web application is MyWebApp, requests for `http://myhost:8080` are redirected to `http://myhost/MyWebApp`, and the welcome file is used.
Maximum Threads	The maximum number of threads allocated for HTTP requests. WARNING! If you increase this value, you must also increase the maximum number of threads on the Resources tab—see “Resources”.	25	The maximum thread setting allows you to balance memory resources. A maximum value set too high needlessly uses memory resources. Monitor the total number of hits listed in the httpstat.dat file for indications of a heavily loaded server. Adjust the maximum thread setting as necessary.
Send “Server” Header in HTTP Response	If selected, EAServer adds the “Server” response header field to each HTTP response.	Disabled	This optional HTTP response header field contains a description of the server software.
Keep Statistics	Select to log statistics.	Disabled
Statistics File Name	If you select to keep statistics, specify the log file name.	Jaguarhttpstat.dat	/work/logs/Jaguarhttpstat.dat (UNIX) C:\work\logs\Jaguarhttpstat.dat (Windows)
Frequency (Seconds)	If you select to keep statistics, specify how often to log them.	36000 seconds (10 hours)
Log Type	You can select All Logs or one of these log types: Request log Error log	All Logs	If you select All Logs, the directory, file size, and truncate options apply to all the log files.
Enable Logging	Select to enable logging.	Enabled
Log Directory	The directory where the log files are stored.		See “HTTP logging and statistics” for information about the log files.
Log File Size	The size, in bytes, to which the log file grows before it is truncated.	Unlimited. If you do not enter a value, log size is unlimited.
Truncate Log on Startup	When this flag is set, the log truncates every time the server is restarted.	The default is to not truncate on start-up.	If the server crashes and this flag is set, you will lose the log file and the information it contains.
Extended Log File Format	If enabled, EAServer writes to the request log using the extended log file format (ELFF), instead of the common log format.	Disabled. By default, common log format is used for the request log.
ELFF Items	When ELFF is enabled, specifies what items to include in each record.	See comments.	For the syntax and default values, see com.sybase.jaguar.server.http.elffitems.
