[Cppcms-users] out() << timezone & redirecting

[Pavel K. <un...@fu...>]

hello Artyom,

		in my app i have overloaded main function where i catch db 
exceptions incompatible with life and set up several things. one of them is 
timezone>

response().out() << booster::locale::as::time_zone( tz );

but that causes setting ostream_requested_ & makes redirecting

response().set_redirect_header( ... )

impossible. is there a better way how to set timezone for each response 
separately or way how to hack it?

pavel.

The problem is once you request output stream the headers are written and thus
you can't set redirect headers.

You need to provide headers first (set redirect header or so)

and then request output stream

Requesting output stream triggers many things including
headers write and saving session values.

So instead of 




Use


response().set_redirect_header( ... )

response().out() << booster::locale::as::time_zone( tz );

I mean
---------

So instead of 

  response().out() << booster::locale::as::time_zone( tz );
  response().set_redirect_header( ... )

Use

  response().set_redirect_header( ... )
  response().out() << booster::locale::as::time_zone( tz );

ok, it seems that if i want to use it in "automatic way" i need to move it to 
overloaded render method and in other cases call it manually.

i overlook that possibility. it's ellegant too.

thanks
