HttpRuntime, threading, cache, and Server.MapPath

I am running some threaded operations within my ASP.NET app, in order to add
some data to the Cache. I know enough to use the HttpRuntime.Cac he instead
of the HttpContext.Cac he, but my operations need to reference a file on the
server. Normally, I'd use Server.MapPath to get the file reference, but I
can't do that within the thread. What can I use instead?

I'd tried using Server.MapPath in Application_Sta rt to give it to an
Application variable, but I can't reference Application in my thread either.

Close. In Application_Sta rt store the physical root in a static (shared in
VB) variable. That you can see from everywhere.

Hi, I have a config XML file that I am using from the application cache. I have configured the entry with a remove callback to re-populate cache automatically when the XML file changes. All is well until the XML file is changed. The cached item is being removed as I would expect, but the remove callback is not firing at all, hence a NullReferenceException is being raised when I try to access the cache object. Please see code snippet...

I want to dynamically create a JavaScript file and cache it on the client for re-use. I know how to write javascript to a web page from the code behind, but I don't know how to actually create a file such as MyNewScript.js and then cache that on the client so all the pages of that session can use it. Can this be done? Thanks -- moondaddy@nospam.com

I have googled to try and find an answer to this issue, but everything I found beats around the bush. I have a web service that calls a DLL. In the DLL, I want to cache the small table data into server cache rather than hit the DB each time, since the data does not change for at least a day.

Hello First of all, sorry for my bad english ;) I have a USER class that i create to every user that enters the website (not neccesarily logged in). At the same time i insert it into a the HttpRuntime.Cache if it doesn't exist. In every request i verify if the user is in the Cache so i don't have to create it again. If it exists, i instantiate an USER object with the Cache object already saved. this is more or less the idea

Is it advisable to store my own data as XML in the folder returned by HttpRuntime.CodeGenDir? (i.e. in "Temporary ASP.NET Files") Each web service on the server must try to read its own cached file when it (re)starts. If it 's not present, it retrieves it from a remote service and caches it locally. If it's not advisable, what is the "best practice" for caching global

Hi I'm running an ASP.NET web application under IIS. I'm inserting a cache object with a file based CacheDependency. I've noticed that when the file changes the Cache object is not always immediately invalidated. e.g. Cache.Insert("myobj", data, new CacheDependency(filePath)); When I make a change to the file 'filePath' and call the object from the cache it is not null. I'm disposing of the FileStream object immediately

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
