Hi Rainer, Pfa the config files in txt format.I tried with the combinatrions available in the settings marked with comments.
Also,could you pl let me know the following: - Will the access log contain an entry for each request that is seen in the jk log?I can see a corresponding entry in the accesslog for an entry in the jk log in my local setup.But I coulnt interpret the same from my prod log.I hope getting this will provide some direction on what element is creating the timeout as from the prod log I can see one entry haing the a timeout in the same time perios as that of the other requests.Pl let me know how to interpret the files.I have sent you the prod log file in my prev mail.Pl let me know if you would like to resend the same or any other details.I too the all entries around 13:44:08 from both logs from prod.

(Also,pl note that we > have currenlty turned off akamai in prod and the timeout is seen > without akamai as well) Let's start in the right way, first fix the configuration, then do and analyze the tests, maybe resulting in more config optimization. Please post your config. I had a quick look at the files you attached, but it looks very much like we first need to improve the config, before analyzing behaviour, that will likely not appear with the right config. > Also,reg your explanation about akamai,I can contact akamai to find > out if they can handle the prematurely closed data differently.Do you > remember any setting to the browser to interpret this invalid data > based on content length/premature closure?(just for testing though > wouldn't apply to real life scenario) No there is no such browser setting that I'm aware of. But akamai is not a browser, its a server that behaves more like a cache. So they need to solve a server problem, not an end user problem. They should immediately invalidate content, that was delivered over a connection that had a protocol abort. > Thanks much for your help.I can give you a call if you would like to > discuss this over phone. Lets first check the config, maybe then everything will be fine ;) Regards, Rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org Please do not print this email unless it is absolutely necessary.

# # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "C:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the # server as "C:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log". # # NOTE: Where filenames are specified, you must use forward slashes # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). # If a drive letter is omitted, the drive on which httpd.exe is located # will be used by default. It is recommended that you always supply # an explicit drive letter in absolute paths to avoid confusion. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen *:80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule asis_module modules/mod_asis.so LoadModule auth_basic_module modules/mod_auth_basic.so #LoadModule auth_digest_module modules/mod_auth_digest.so #LoadModule authn_alias_module modules/mod_authn_alias.so #LoadModule authn_anon_module modules/mod_authn_anon.so #LoadModule authn_dbd_module modules/mod_authn_dbd.so #LoadModule authn_dbm_module modules/mod_authn_dbm.so LoadModule authn_default_module modules/mod_authn_default.so LoadModule authn_file_module modules/mod_authn_file.so #LoadModule authnz_ldap_module modules/mod_authnz_ldap.so #LoadModule authz_dbm_module modules/mod_authz_dbm.so LoadModule authz_default_module modules/mod_authz_default.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authz_host_module modules/mod_authz_host.so #LoadModule authz_owner_module modules/mod_authz_owner.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule autoindex_module modules/mod_autoindex.so #LoadModule cache_module modules/mod_cache.so #LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule cgi_module modules/mod_cgi.so #LoadModule charset_lite_module modules/mod_charset_lite.so #LoadModule dav_module modules/mod_dav.so #LoadModule dav_fs_module modules/mod_dav_fs.so #LoadModule dav_lock_module modules/mod_dav_lock.so #LoadModule dbd_module modules/mod_dbd.so #LoadModule deflate_module modules/mod_deflate.so LoadModule dir_module modules/mod_dir.so #LoadModule disk_cache_module modules/mod_disk_cache.so #LoadModule dumpio_module modules/mod_dumpio.so LoadModule env_module modules/mod_env.so #LoadModule expires_module modules/mod_expires.so #LoadModule ext_filter_module modules/mod_ext_filter.so #LoadModule file_cache_module modules/mod_file_cache.so #LoadModule filter_module modules/mod_filter.so #LoadModule headers_module modules/mod_headers.so #LoadModule ident_module modules/mod_ident.so #LoadModule imagemap_module modules/mod_imagemap.so LoadModule include_module modules/mod_include.so #LoadModule info_module modules/mod_info.so LoadModule isapi_module modules/mod_isapi.so #LoadModule ldap_module modules/mod_ldap.so #LoadModule logio_module modules/mod_logio.so LoadModule log_config_module modules/mod_log_config.so #LoadModule log_forensic_module modules/mod_log_forensic.so #LoadModule mem_cache_module modules/mod_mem_cache.so LoadModule mime_module modules/mod_mime.so #LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule negotiation_module modules/mod_negotiation.so #LoadModule proxy_module modules/mod_proxy.so #LoadModule proxy_ajp_module modules/mod_proxy_ajp.so #LoadModule proxy_balancer_module modules/mod_proxy_balancer.so #LoadModule proxy_connect_module modules/mod_proxy_connect.so #LoadModule proxy_ftp_module modules/mod_proxy_ftp.so #LoadModule proxy_http_module modules/mod_proxy_http.so #LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so #LoadModule speling_module modules/mod_speling.so #LoadModule ssl_module modules/mod_ssl.so #LoadModule status_module modules/mod_status.so #LoadModule substitute_module modules/mod_substitute.so #LoadModule unique_id_module modules/mod_unique_id.so #LoadModule userdir_module modules/mod_userdir.so #LoadModule usertrack_module modules/mod_usertrack.so #LoadModule version_module modules/mod_version.so #LoadModule vhost_alias_module modules/mod_vhost_alias.so <IfModule !mpm_netware_module> <IfModule !mpm_winnt_module> # # If you wish httpd to run as a different user or group, you must run # httpd as root initially and it will switch. # # User/Group: The name (or #number) of the user/group to run httpd as. # It is usually good practice to create a dedicated user and group for # running httpd, as with most system services. # User daemon Group daemon </IfModule> </IfModule> # 'Main' server configuration # # The directives in this section set up the values used by the 'main' # server, which responds to any requests that aren't handled by a # <VirtualHost> definition.
