HTTP Header too long error, PLEASE HELP!
I am getting the "HTTP Header too long" error on the WebServer (running on
NT) when processing request from the client runing on zOS. The same client
java app running on NT does not cause this error on the same WebServer.
I looked at the source code (WebServer.java), the IOException (HTTP Header
too long) is thrown when the buffer size is > 512.
My question is: why the same java client code causes the buffer overflow on
the same WebServer (on NT) when run on the zOS (IBM) but not when run on NT?
And how do I get around this problem?
Thanks in advance for the help.

Oh my, of course: we're not even doing anything useful with those headers!
Thanks John.

Hannes,
I have a small buffer for the header and just throw away any bytes that
don't fit in. The only headers I'm interested in for XML-RPC are not going
to be long so I don't care about the very long ones.
This seems to me to be a slightly more robust approach.

Look at what Apache httpd does...or even Tomcat's httpd.

Obviously the 512 byte limit is to short.
Any idea what a good assumption would be for the maximum size of a
single HTTP header?
1k? 2k?

I just increased the buffer size from 512 to 2048 bytes. If you use the
latest version from the CVS, you shouldn't see this error again (unless
your client sends some abnormally large HTTP header).
