http://issues.apache.org/bugzilla/show_bug.cgi?id=38546 Summary: Google bot sends invalid If-Modifed-Since Header, Tomcat throws exception Product: Tomcat 5 Version: 5.0.28 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Not sure if this is fixed in the recent versions, or even if it should be, but thought it should be noted somewhere. Feel free to close this as invalid, since it isn't tomcat's fault. When being crawled by the google bot (User-Agent: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)) the following exception gets thrown on each of the servlets I've deployed that implement the getLastModified () call. java.lang.IllegalArgumentException: Mon, 06 Feb 2006 17:14:33 at org.apache.coyote.tomcat5.CoyoteRequest.getDateHeader (CoyoteRequest.java:1887) at org.apache.coyote.tomcat5.CoyoteRequestFacade.getDateHeader (CoyoteRequestFacade.java:426) at javax.servlet.http.HttpServlet.service(HttpServlet.java:691) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter (ApplicationFilterChain.java:237) I'm pretty sure the error is Google's. The RFC requires a timezone to be appended for date headers (and more specfically a GMT timezone), which this one doesn't have. Would it be possible to have tomcat simply throw a warning here ? It is a recoverable error if we assumed the timezone was GMT if omitted, and logged as an invalid timestamp ? Or possibly even trapped, logged as a warning and assumed to be not supplied (i.e. = 1970). I understand this is probably not a tomcat bug, and I will lodge it with the Google bot support as well, but wondered whether it might not be a good robustness thing to add in anyway. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
