Dear, I finally figure out how to log!!
The SimpleLog can't work, but the log4j works. Below is the log. executing: POST https://127.0.0.1/agent/xml/login.xml HTTP/1.1 ---- DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.max-redirects': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection-manager.timeout': null DEBUG [org.apache.http.impl.conn.SingleClientConnManager] SingleClientConnManager.getConnection: HttpRoute[{s}->https://127.0.0.1] DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.timeout': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.socket.timeout': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.tcp.nodelay': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.socket.timeout': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.socket.linger': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.socket.buffer-size': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.element-charset': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.max-line-length': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.element-charset': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.max-header-count': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.max-line-length': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.max-status-line-garbage': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.connection.stalecheck': null DEBUG [org.apache.http.impl.client.DefaultClientRequestDirector] Stale connection check DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.virtual-host': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.default-headers': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.useragent': Apache-HttpClient/4.0-alpha3 (java 1.4) DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.expect-continue': true DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.cookie-policy': null DEBUG [org.apache.http.client.protocol.RequestAddCookies] CookieSpec selected: best-match DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.cookie-datepatterns': null DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.single-cookie-header': null DEBUG [org.apache.http.impl.client.DefaultClientRequestDirector] Attempt 1 to execute request DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.wire] >> "POST /agent/xml/login.xml HTTP/1.1[EOL]" DEBUG [org.apache.http.wire] >> "Content-Length: 225[EOL]" DEBUG [org.apache.http.wire] >> "Content-Type: application/x-www-form-urlencoded[EOL]" DEBUG [org.apache.http.wire] >> "Host: 127.0.0.1[EOL]" DEBUG [org.apache.http.wire] >> "Connection: Keep-Alive[EOL]" DEBUG [org.apache.http.wire] >> "User-Agent: Apache-HttpClient/4.0-alpha3 (java 1.4)[EOL]" DEBUG [org.apache.http.wire] >> "Expect: 100-Continue[EOL]" DEBUG [org.apache.http.wire] >> "[EOL]" DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.headers] >> POST /agent/xml/login.xml HTTP/1.1 DEBUG [org.apache.http.headers] >> Content-Length: 225 DEBUG [org.apache.http.headers] >> Content-Type: application/x-www-form-urlencoded DEBUG [org.apache.http.headers] >> Host: 127.0.0.1 DEBUG [org.apache.http.headers] >> Connection: Keep-Alive DEBUG [org.apache.http.headers] >> User-Agent: Apache-HttpClient/4.0-alpha3 (java 1.4) DEBUG [org.apache.http.headers] >> Expect: 100-Continue DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.wait-for-continue': null DEBUG [org.apache.http.wire] << "HTTP/1.1 100 Continue[EOL]" DEBUG [org.apache.http.headers] << HTTP/1.1 100 Continue DEBUG [org.apache.http.impl.client.ClientParamsStack] 'http.protocol.version': HTTP/1.1 DEBUG [org.apache.http.wire] >> "jaxbString=%3C%3Fxml+version%3D%221.0%22+encoding%3D%22UTF-8%22+standalone%3D%22yes%22%3F%3E%0A%3Clogin%3E%0A++++%3CphaseKey%3Epowerpanel.encryption.key%3C%2FphaseKey%3E%0A++++%3Cresult%3E-1%3C%2Fresult%3E%0A%3C%2Flogin%3E%0A" DEBUG [org.apache.http.wire] << "HTTP/1.1 302 Moved Temporarily[EOL]" DEBUG [org.apache.http.wire] << "Server: Apache-Coyote/1.1[EOL]" DEBUG [org.apache.http.wire] << "Set-Cookie: JSESSIONID=A8DEFC59DB38202BBEF794ABF9556991;

However, it specifies both a domain "127.0.0.1" and a path "/agent". If your next request is NOT to 127.0.0.1, then the cookie will not be sent. The comparison is on the string level, so if the next request goes to "localhost" instead of "127.0.0.1", then it will NOT match. Also, if your next request does not go to a path starting with /agent, this cookie will not match. cheers, Roland --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
