Public API changes

A JSP/servlet can dynamically create a URL using public methods on the HttpRequest object to get the server’s port, protocol, and host. When configured with a redirector, the sever’s port, protocol, and host differ from the redirector. As a JSP/servlet developer, you may decide to redirect JSPs/servlets to the redirector’s host/port instead of the server’s. To facilitate this in EAServer 5.x, the com.sybase.jaguar.webapplicaiton.getServerInfoFrom was used. The EAServer 6.0.2 equivalent is the application server property httpGetServerInfoFrom. This property can have one of three values: “server,” “proxy,” or “source.” Table 4-3 describes the various javax.servlet.http.HttpRequest methods.

**Table 4-3: Modified APIs**
HttpRequest method	Server	Proxy	Source
getServerName()	Gets the name of the server being redirected to	Gets the name of the server using the httpDomain property	Gets the name of the server as typed into the browser
getServerPort()	Gets the port of the server being redirected to	Gets the proxy port from httpsProxyPort or httpsProxyPort	Gets the port of the server as typed into the browser
getProtocol()	Gets the protocol that was used to connect to the server	Gets the protocol from httpProxyProtocol	Gets the protocol as typed into the browser

The EAServer 6.0.2 default value is “proxy.” If the required property is not set (httpDomain, httpProxyPort, httpsProxyPort, or httpProxyProtocol), then a value of “source” is used.

See Chapter 3, “Creating and Configuring Servers,” in the EAServer System Administration Guide for information about setting “Get Server Info From.”
