[opencms-dev] Add Header doesn't work

[Carsten Wilhelm]

Hi,

I'm using the Formgenerator module and try to download the data using the standard export function.
After choosing start and enddate I get the exported CSV data within the same browser window, Content-Type is text/html.

Playing around it seems that the changes to the Response headers doesn't seem to be working. Is it possible that some content was already sent by OpenCms and therefore no modifications to the HTTP headers are possible any more?

Same for redirects.

Is there any way to cache output, so that I can change http headers from own modules or dynamic functions?

Currently we haven't changed anything on the flex cache settings - everything is exactly the same as in standard installation.

Kind regards,
Carsten
