Hi, In the effort of developing a Cache scheme wich would work for highly dinamic data, and where the called page might be called with an enormous amount of dif query strings, I stumbled with a little problem... I need to call a rendered url, passed the REQUEST and wanted to do it directly to the self var. Not being able to do it, I have come with the solution of calling urllib with URL1, the called object and '?' + the query string... Not that fancy, but it works... slowly but smoothly. I am having a bit of trouble, though, when calling this Cache with 1000 connections and 100 simultaneous. The server times out and commits a silent suicide. It keeps working as far as the start script is concerned, but no longer responds to any requests. I have only the fact that I can call a dtml method with the values above with no trouble at all as a clue, so any pointer will be quite welcome. the cache prod is called CachePool and is available in: http://www.zope.org/Members/neli/CachePool -- Carlos Neves cneves@ruido-visual.pt
