partial page display
I would like to have some of the page display while the rest of the data for the page is still being retrieved (i.e. a Please wait, this operation takes several seconds... kind of message). I thought (perhaps naively) that a print Please wait.\n; at the beginning of my handler would accomplish this, but mod_perl seems to cache all output until the entire handler has returned. Is this possible without the use of a module like CGI::Push? Perhaps I need to modify the header? Thanks, Fran

RE: partial page display
That doesn't work for us. It seems that the browser also maintains a buffer, because if I loop the please wait message 1 times, it does show up immediately. I suspect possibly there's some massaging we can do to the header?

Re: partial page display
Add a BR/ tag. That's what I throw in to force the browser to flush whatever I fed it onto the screen...

RE: partial page display
Thanks, finally found the right combination...
{
local $| = 1;
$r-content_type('text/html');
$r-send_http_header;
print Testing...\n;
}

Nope, especially when you *can* control the HTTP response headers. This HTML extension is not supported by all browsers. See http://marc.theaimsgroup.com/?l=apache-modperlm=103658812122901w=2 Instead you should use the HTTP headers to do that.

I hope so, because I'm using it. One problem with meta-refresh is that it breaks the browser back button. After the refresh occurs and the new page is displayed, if the user hits the back button they wind up back at the meta-refresh page. This can be confusing for users, especially with a short delay.
