Pardon my ignorance .. but browsing thru the application directories I found a number of other file types like css, javascript, ser etc and wasnt sure whether these need to go to tomcat or not. Hence -> JkMount /LCSW/* ajp13
So I went with with I am sure about, which is image files and html pages. Nobody in my shop knows this side of the application and vendor support is terrible. ________________________________ From: Christopher Schultz <ch...@christopherschultz.net> To: Tomcat Users List <users@tomcat.apache.org> Sent: Wednesday, May 27, 2009 10:31:20 AM Subject: Re: Tomcat not closing threads -- SOLVED ?? -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Chetan, On 5/26/2009 2:47 PM, Chetan Chheda wrote: > After some digging thru config files setup by the vendor, I think I > might have found the root cause ..Correlating the access_log and tomcat > logs, I found out that tomcat threads were shooting up whenever a large > number of GIF files were being requested. > > These are the modjk settings in our application config files that > are included in httpd.conf > JkMount /LCSW/* ajp13 > JkMount /LCSW/*.jsp ajp13 > JkMount /LCSW/*.jsp/* ajp13 As André points out, the second and third line are superfluous, given the first line. > So when an image is accessed via the following URL, > http://blahbhal/LCSW/images/header.gif , the above routes were sending > it to tomcat.

Something like: JkMount /LCSW/*.jsp ajp13 > I tested the above in a test environment and was able to access a > gif file with tomcat down. Try the above. I think you'll like it better, since you won't have to add exceptions for every type of static file you want to serve. > my question is, how does the ajp13 connector interpret a gif > file/static content request as opposed to a jsp request? mod_jk does not do any interpretation at all. The JkMount directives just set up a table of URL pattern matchers. No content is analyzed or anything like that. In combination with another module, you might be able to sniff some of the /request/ and then conditionally invoke Tomcat (by using André's favorite "SetHandler jakarta-servlet" trick) but that would be considered super-human efforts to do something that ought to be simple. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkodTrgACgkQ9CaO5/Lv0PAZLACgwBc8vKC66xVRYrd+HJoYtmcf sKwAn0bx7DlKzROMeIV0zhjQ/VSXB0zc =Sxs5 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
