WEB-INF (Tomcat) and .htaccess (httpd)

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

WEB-INF (Tomcat) and .htaccess (httpd)

Apache Tomcat's WEB-INF directory is rather like Apache httpd's ".htxxxxx" files - they both contain data which is within the document directories, but is configuration data that's not directly visible to the web.

WEB-INF/web.xml (Tomcat) contains the extra configuration information for the current directory / application that's needed in addition to the web.xml file in the main configuration file, and that can be directly compared to the .htaccess files under httpd, which contain additional configuration data, per directory, in addition to what's in the httpd.conf file.
