Method Detail

closeInputStream

public void closeInputStream()
                      throws java.io.IOException

closing the input stream does not close the socket

Overrides:

closeInputStream in class ServletConnection

close

public void close()
           throws java.io.IOException

called at the end of a request by response.finish() or just before closing output streams by out.close() The proxy protocol never closes the socket connection at this point, we just send a FINISH to let the native connector know we're done with the request.

readRequest

protected void readRequest()
                    throws java.io.IOException

get a new request object over the proxy connection. This method does not return until a new request is received, but in the mean time it processes any proxy-level commands, such as PROXY_PING and PROXY_GET_PROPS

Overrides:

readRequest in class ServletConnection

proxyGetProps

protected void proxyGetProps()
                      throws java.io.IOException

service the PROXY_GET_PROPS command

getRealPath

public java.lang.String getRealPath(java.lang.String path)

Returns corresponding real path for specified virtual path. Values are cached. The cache is local to this endpoint, so it can return values specific to the webserver we're connected to.

Overrides:

getRealPath in class ServletConnection

getSessionId

public java.lang.String getSessionId()

Specified by:

getSessionId in interface ProxyEndPointInterface

setServerLoad

public void setServerLoad()

run

public final void run()

Specified by:

run in interface java.lang.Runnable

writeStatus

public void writeStatus(int status,
                        java.lang.String reason)
                 throws java.io.IOException

Overrides:

writeStatus in class ServletConnection

writeHeader

public void writeHeader(java.lang.String name,
                        java.lang.String value)
                 throws java.io.IOException

Overrides:

writeHeader in class ServletConnection

commit

public javax.servlet.ServletOutputStream commit()
                                         throws java.io.IOException

getHeader

public java.lang.String getHeader(java.lang.String name)

Get the header value from the set of headers we received on the initial request. If the header value is not found, go back to the web server and ask for it. If we get it this way, store it in the extraHeaders table so we don't get CGI headers and HTTP headers mixed up. This is mainly for spec conformance.

Overrides:

getHeader in class ServletConnection

getHeaders

public java.util.Enumeration getHeaders(java.lang.String name)

Overrides:

getHeaders in class ServletConnection

getHeaderNames

public java.util.Enumeration getHeaderNames()

Overrides:

getHeaderNames in class ServletConnection

parseHeaders

protected void parseHeaders(java.lang.String header)

parse a JRun 2.3 style connector request. In this case, the header comes accross as a single string, and we must parse everything apart manually

getRemoteAddr

public java.lang.String getRemoteAddr()

Overrides:

getRemoteAddr in class ServletConnection

getRemoteHost

public java.lang.String getRemoteHost()

Overrides:

getRemoteHost in class ServletConnection

getServerName

public java.lang.String getServerName()

Overrides:

getServerName in class ServletConnection

getServerPort

public int getServerPort()

Overrides:

getServerPort in class ServletConnection

getRequestURI

public java.lang.String getRequestURI()

Overrides:

getRequestURI in class ServletConnection

getQueryString

public java.lang.String getQueryString()

Overrides:
