Subject RE: fail to download large static files in tomcat
Date Tue, 28 Jun 2011 07:44:54 GMT
The useSendfile relates to connectors, the configuration I understand is needed is in under
Engine > Host > Context (<Context            docBase="../../work/bundles"       

Can you explain how the " useSendfile" relates to static files?
Is the configuration I am using correct? Or is there another way to configure the use of static
Thanks, Michal

What failed ? How failed ? what do the logfiles say ?

Not without some better data.

As far as I know, there is no limit (on the Tomcat side) for *downloading* files.

What do you mean by "too heavy" ? at the level of the client, or the server ?
(or the bandwidth of your communication channel client(s)<->server ?)

I don't think that this would be either recommended or not recommended.  It is something 
that you /can/ do with Tomcat (or any other webserver).
If these are always large static files, you may want to look at a parameter somewhere 
named "useSendFile" or similar, probably in the <Connector> documentation.
