Jeff, Sometimes, usually when under heavy load, the web server may be able to receive requests but unable to process them due to low resources (most commonly worker threads). In such a case the web server may simply have no other choice but to drop the connection without sending back any status code. This in turn causes HttpClient to throw a HttpRecoverableException "unable to find line starting with "HTTP""
Can it be that you have been stressing the server a bit too much? Anyways, usually "unable to find line starting with "HTTP"" exception is not a HttpClient fault, but that of the target server. The regrettable thing about it it is a poor choice of exception class name and a misleading error message. (This problem has already been fixed in HttpClient 3.0) Hope this helps a little Oleg On Tue, 2004-10-05 at 08:27, Jeff Fern wrote: > Hello all, > > I am running Tomcat 5.0.27 with Java 1.4.2 on my local machine (Debian > sarge).
