I had to increase that parameter once for another reason.. the headers sent from certain logins would be larger than the default 8192 bytes (8K). This was caught when we logged the packets sent and received from IIS where tomcat was serving as a jsp engine. We saw no negatives on increasing it. If I recall right, we had set it to much higher than 32K

Good job. -John On Thu, Mar 22, 2012 at 7:12 AM, Jiri Pospisil <jiri.pospi...@lchclearnet.com> wrote: ** Thanks all for their suggestions. The issue was at the end with maxHttpHeaderSize parameter in Tomcat configuration. It was set to 8K, but this was not enough for some users when being authenticated because Kerberos token sent in the header was larger than 8K and the result was broken HTTP request. The token seems to get bigger if the person is a member of many groups (hence only some users being affected). Changed the parameter to 32K and this resolved the issue. Not sure if there is any downside of having this set to a higher number, but so far have not seen any issues.

OurMidTier is a DNS alias for the physical box or a loadbalanced VIP? 2. Try tracert or telnet from the client computer having issues. 3. Try with full domain ex: http://ourmidtier.abc.com/arsys/home, I have seen in the past depending on the network rules it had worked if you specify FQDN but not with the shortDNS.

We are running mid-tier on a Windows machine and users access it via link such as http://OurMidTier/arsys/home where OurMidTier is a DNS alias of that physical box. The above link works for many users but we have some users who just get page cannot be displayed error in their browser. When we look on their machine, they can ping the alias. We also flushed the DNS cache on their PC but to no avail. What is even stranger is that if we use IP address of the mid-tier box, it connects successfully, so http://10.20.30.40/arsys/home works fine and open the home page. Then on the home page, the overview console returns message Unable to set up data connection ... (ARWARN 9351). Other consoles seem to work fine; it is only overview which I believe uses a plug-in behind it. I have tried running the Fiddler tool on the affected PC. It seems to connect to the web server and then the connection gets simply closed (admittedly, I have only a limited knowledge in that area). Has anybody seen such behaviour before? We are on AR Server 7.6.03 patch 002 for server as well as mid-tier. Browser – tested with IE 7 as well as IE 8 Web server OS – Windows 2003 (64 bit) Java - 1.6.0_26 (64 bit) Web Server - bundled Apache Tomcat - 6.0.20 Thanks for any suggestions.
