问题 I've read every question (I believe) about image caching and they mostly address the refesh issue. What I need to do instead, is to "get rid" once and for all of cached images loaded through a JS script. Backrgound: as part of a tool available on a public website, I need to load images from random websites and analyze them, without the need for displaying them. In summary it's just a loop with a function like this (which works fine): var img = new Image(); img.onload = function(){//analysys};

问题 I'm testing a query in neo4j and I see that when I clear the cache . Neo4j takes more time to load . which mean performances are dicreasing . Why is this happening I don't know now whether to clear the cache for each query ? or should I just test without clearing the cache 回答1: Neo4j browser doesn't cache any data from a query. So clearing your browser cache has no incidence on the query execution time. Perhaps the browser is creating a new connection to the database, makes some computations

问题 I have a DataTable with about 10,000 rows in it. I would like to store this data once for aspx page. When the user selects different options in the page, data is further selected from the already stored DataTable. I tried using the ViewState, but as soon as the data grows beyond 100 rows, performance degrades. Where should I store this data? 回答1: Is the data on a per-user basis or is it global for all users? If it's global, use Cache. If it's user-specific, the traditional answer is to use

问题 I am writing an application whose purpose is to optimize a trading strategy. For the sake of simplicity, assume only that we have a trading strategy that says "enter here", then another that says "exit here if in a trade" and then lets have two models: one says how much risk we should take (how much we lose if we're on the wrong side of the market) and the other says how much profit we should take (i.e. how much profit we will take if the market agrees). For simplicity sake, I will refer to

问题 I have in the app a lot of string requests done in volley. In each module there is a different onResponseListener doing always something different. And I need to make them work also offline. So I am getting the response from the cache. Problem is that there can be a lot of requests called asynchronously with different url. Problem is how to remember the url of the request when getting it from cache. Currently it is only in global variable, but as requests can be sent asynchronously, response
