Open source license

software licensing

Allowing an individual or group to use a piece of software. Nearly all applications are licensed rather than sold. There are a variety of different types of software licenses. Some are based on the number machines on which the licensed program can run whereas others are based on the number of users that can use the program. Most personal computer software licenses allow you to run the program on only one machine and to make copies of the software only for backup purposes. Some licenses also allow you to run the program on different computers as long as you don't use the copies simultaneously

How to enable proxy service security in ESB 4.9.0?

Security is  one of the major concern when we developing API base integrations or application developments. WSO2 supports WS Security , WS-Policy and WS-Security Policy specifications. These specifications define a behavior model for web services. Proxy service security requirements are different from each others. WSO2 ESB providing pre-define commonly used twenty security scenarios to choose based on the security requirements. This functionality is provided by the security management feature which is bundled by default in service management feature in ESB. This configuration can be done via the web console until ESB 4.8.1 release, but this has been removed from the ESB 4.9.0. Even though this feature isn't provided by the ESB web console itself same functionality can be achieved by the new WSO2 Dev Studio . WSO2 always motivate to use dev studio to prepare required artifacts to the ESB rather than the web console. Better way to explain this scenario is by example. Following...

How to preserving HTTP headers in WSO2 ESB 4.9.0 ?

This is because most of the time certain important headers are removed or modified by the applications/middleware which run the communication. The previous version of our WSO2 ESB, version 4.8.1, only supported “ server ” and “ user agent ” header fields to preserve with, but with the new ESB 4.9.0, we’ve introduced a new new property ( http.headers.preserve ) for the passthru ( repository/conf/ passthru-http.properties ) and Nhttp( repository/conf/ nhttp.properties ) transporters to preserve more HTTP headers. Passthru transporter – support header fields               Location Keep-Alive Content-Length Content-Type Date Server User-Agent Host Nhttp transport – support headers Server User-Agent Date You can specify header fields which should be preserved in a comma-separated list, as shown below. http.headers.p...
