Re: [Cppcms-users] Can't jump to another page from server side

[Artyom B. <art...@ya...>]

Can you send a headers that are returned by the web server, for example
simulate the request with wget

wget -d http://some/url

And provide output (-d debug - prints all headers)

So we can see what is send by the server.
