1. "206 Partial Content", so it was a request containing a Range header. Using an HTTPD in front of Tomcat, you would be using the AJP connector (which differs from your original configuration of "http bio"). So the issue is reproducible in that configuration as well? %X is a feature in HTTPD access log format. Tomcat does not implement it. What is in Tomcat's own access log? The same request? 2. I my test (connecting to Tomcat directly over http with Adobe Reader 10.1.3), the only access log line is "200", transferring the whole document. So why a ranged request comes? A feature of Acrobat 9? I wonder what range headers are in it. > The security zone is "internet". > To reproduce the issue: > Utilize the acrobat integrated in the browser > Install a new tomcat 7.x on a linux machine, not windows with tar zxf > apache-tomcat-7.x.tar.gz > Put the pdf in any webapp, the ROOT is enough. > Obviously use a recent jvm, I use latest version of 1.6 (.33) > Start the tomcat (sh catalins.sh run or what you prefer) > Point the browser to the url. > Every time you want to retry, just empty the browser's cache and kill the > explorer process. > Tomcat >= 7.0.27 the error occurs > Tomcat < 7.0.27 the error has gone. > Michele Masè > > On Mon, Jul 30, 2012 at 12:45 PM, Konstantin Kolinko <knst.koli...@gmail.com >> wrote: > >> 2012/7/30 Michele Mase' <michele.m...@gmail.com>: >> > I've the following problem: the server is running tomcat 7.0.27 (but also >> > with 7.0.28 and 7.0.29) and from the client (ie + acrobat 9) when opening >> > some pdf docs I receive an error complaining about a network error: >> > >> > "A network error occured while accessing this document on interntet. >> Would >> > you like to close the document or reload it?" >> > >> > Reverting back to 7.0.26 the problem disappears ... >> > >> > The connector is the http bio >> > >> > >> > This is one public pdf that caused me the error when i put it on a tomcat >> >>=7.0.27 >> > >> > >> http://www.regione.fvg.it/rafvg/export/sites/default/RAFVG/formazione-lavoro/agenzia-regionale-lavoro/allegati/joblab_2.0_scheda_tematica_1_FR.pdf >> > >> > >> > What happened to the bio connector under the 7.0.27 version that could >> > cause the issue? >> > >> > The connector uses the standard roles, for example: >> > >> > <Connector port="8080" protocol="HTTP/1.1" >> > connectionTimeout="20000" >> > redirectPort="8443" compression="off"/> >> > >> >> 1.
