Sounds like a buffered file. Note, that Zope was not designed for immediate streaming -- even when you use "HTTPResponse.write". In general: the "Content-Length" is required for "HTTPResponse.write" (at least for some browsers). When ZServer sees a large "Content-Length", it serves the content via a temporary file to make content delivery to the (potentially slow) client independent from the Zope worker process and to reduce memory load. This means: the output from the worker process is written to a temporary file and later served from this file by ZServer independent from Zope. You may try to work around this by setting "Content-Length" to "0". In this case, some browsers will require a "Connection: close" header to be able to work correctly with the streamed content. Note that intermediate HTTP clients (Apache, Proxies, ...) may buffer the content in a way similar to ZServer. Thus, in general: HTTP is not well suited for streaming... -- Dieter _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
