Note: Readers are cautioned that the Growth percentages are based on a module's market share penetration rather than the absolute number of modules we detected. Thus, it is possible for the number of modules to increase, while the growth is actually a negative value.

Looking for a specific module? Check the module registry at http://modules.apache.org

Note: OpenSSL, BSafe, and SSLeay aren't true modules in their own right; rather they are required for a number of SSL enabling modules, and will often have their signature string imbedded into the server string, thus allowing us to determine which of them is being used. Rather than separate this out into a separate report, we've included them here.
