• Re: Difference between ASP.net and VB.net

  ASP.Net is the technology for programming the Web Application.WebForms are part of ASp.Net as Windows Forms are for Windows Application.

• Re: Cache deleted with no reason

  Itaiz I am not sure what you are asking ... (1) Are you storing information in Session or Cache? (2) Data Cache in ASP.Net does not depend on session and is stored as part of worker prcocess and will be cleared if IIS is reset of for some reason the ASP.Net worker process has to restart. in IIS 6.0 you can set many parameters to restart ASp.Net process if memory consu,ed reaches certain limit or certain number of requests are served etc. You need to clearify where the data is stored . How it is retrieved

• Re: Static objects unloaded ?

  Roggan remember that Hashtable is always stored by Reference in the Cache. So any changes made to the hashtable will be reflected in the Cached Copy too even if you don't get the Hashtabl from the Cache but use the same Hashtable after storing it in the cache or make any changes to the content after getting it out of Cache.

• Re: caching data from sql database in a web services

  StijnVU Webservice is just like another Web Application as far as ASP.Net Data Cache is concerned.So you will use the same techniques as are used in the WebApplication.

• Re: How to get statistic of each page when user view that page ?

  If you do not want to use commercial products then best think will be to create a WebServices with a method that takes WebSite Name, user name , Page path and other details and log it to the database. You can call the webservice using Asyncyhronous Method call So that the Actual request to the page doesn't spend time processing the log and you also capture all the statistics. For details on asychronous call look at following ... Asynchronous Web Service Calls over HTTP with the .NET Framework you

• Re: Where to Complain, Bandwidth Theft

  yes you can use the HttpHandler to secure image files. That is siimiliar to the approach I mentionedin my first post i.e. you actually has to use Showimage?imagepah i,e change all the liks from just path to ShowImage?path. Here are details Securing Image Url on the Website I don't really like this approach since it involes encrypting the image and lot od extra processing specifically if you have large images or lot of image on the page.

• Re: Where to Complain, Bandwidth Theft

  You need to ask your Hosting Provider to map the image and video files to be handled by ASp>net authorization. Then if you re using winodws or forms authentication and if you website requires users to sign in then then others can't steal your images. In case of anonymous access i.e. public internet site its very hard. you can file complain to individual websites like here at ASP.Net if some one links the image from your website to the post and the moderators here might not allow it because of
