1 CORBA API changes

Common CORBA API logic remained the same as in the version 2.0. Just parameters and some methods names were changed and some new methods were added as well.

The changes are the next:

• HTTPServ.idl file renamed to HTTP.idl.
• createHandler renamed to create_handler. Motivation of those changes is compatibility with idl style OMG recommendations ab/98-06-03
• set_cookie takes as cookie’s life time number of seconds instead of three values (days, hours, minutes). i. е. in your programs you should change calls of type:

  \verb|httpStream->set_cookie(name,value,x,y,z);

  to calls:

  \verb|httpStream->set_cookie(name,value,(((x*24)+y)*60+z)*60);

• the IDL file HTTPServ.idl renamed to HTTP.idl.

Extensions:

• To the RequestInfo structure HTTP request method is added.
• Create handler and request handle methods now can rouse RedirectException exception.
• Setting mechanism of any output request head element is added.
• Packet record mechanism of request head is added.

consequently:

• You should recompile all the modules dependent on HTTP.idl in any case.
• Change createHandler to create_handler
• Change set_cookie calls
• If necessary, study the possibility of new ModCbroker properties use ModCbroker for functionality increase or for enhancement of your software productiveness.

2 Changes in settings parameters

• Before you specified ORB directives by ORB_Args parameter , now by CbrokerORBArgs.
• In Apache-2.0 the way of attaching module handler to request had been changed. So we added CbrokerLocation directive to the configuration - we handle this request if URI directory starts from this parameter .
• Module file name had been changed from libcbroker.so to mod_cbroker.so
• In Unix the file is installed to : <prefix>/libexec/apache2

consequently:

• load module sentence:

  LoadModule cbroker_module <path>/libcbroker.so

  should be changed to

  LoadModule cbroker_module <path>/mod_cbroker.so

• part of Apache-1.x configuration of the following kind:

  <Location cbroker>   SetHandler cbroker-handler   ORB_args -ORBInitRef NameService=cobaloc::my.host.com:2809/NameService   </Location>

  goes to the next form.

  <IfModule mod_cbroker>   CbrokerLocation  cbroker   CbrokerORBArgs -ORBInitRef NameService=corbaloc::my.host.com:2809/NameService   </IfModule>

  And configuration with authorization:

  <Location cbroker>   SetHandler cbroker-handler   ORB_args -ORBInitRef NameService=cobaloc::my.host.com:2809/NameService   AuthType Basic   AuthName myService   require valid-user   </Location>

  goes to

  <IfModule mod_cbroker>   CbrokerLocation  ProtectedCbroker   CbrokerORBArgs -ORBInitRef NameService=corbaloc::my.host.com:2809/NameService   </IfModule>   <Location ProtectedCbroker>   AuthType Basic   AuthName myService   require valid-user   </Location>
