[Zope] queryCatalog API?
Is there an API for the queryCatalog() method? In order words a comprehensive definition of the parameters/arguments it accepts. The only definition I can usually find is that is accepts a catalog_query with no definition of what that may be.

Does your system start swapping? In this case, you need to take urgent counter measures: * provide more RAM * check your configuration that affect memory consumption. The "temporary storage" hosting the sessions is often misconfigured. If you put large amounts of data in your sessions, this may be a considerable memory hog. Maybe, you need to make your ZODB caches smaller or reduce the number of concurrent threads. * check whether your application contains memory leaks. Unfortunately, this is not easy. >Even when traffic is removed from the box - you still get a >large response time (>10s). This is Linux kernel 2.6.18-8.el5xen. Python sits on top of the C runtime memory allocation -- and this allocation does not support compaction. This means that the memory used in your program is likely to be scattered all over the process address space. Therefore, even with small load, you may face large response times when your system is unable to hold the (usally large) working set in memory. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

I had a similar problem with pdf files, and googling indicated that IE
might be deleting the cached copy of the document before the opening
application can get to it.
I have had some success setting cache control to "private". Something
like:
request.response.setHeader('cache-control','private')
"private,must-revalidate" may also be a good value, depending on your
situation.
I Googled back through and found that the problem usually manifests when
you have a 'cache-control':'no-cache' header. The above explanation was
not quite right.
Anyway, either removing the "no-cache" header or using one that allows
the local machine to keep a copy should work, if the problem is in fact
a 'no-cache' header.
