We are planning to introduce Load balancing in our server environment. Our site has lots of thumbnails (Thumbimages) to get displayed on the website. As all the images should be there under Web directory to get displayed on web site, do I need to maintain these TNs in all the servers? Is there any other way to accomplish this?

I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well. The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well. For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind. The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.
I have ran into an issue where I have to use ASP.NET to do a Thumbnail of images uploaded since the hosting company does not have any of the required ASP Classic 3rd party utilities that I can use. I have played around with several different Upload scripts before I found a tutorial on using: Uploadify (Love this script) with ASP.NET. [URL] What I am needing to do with the script is to create Thumbnails of the images that are uploaded, and when I try to do so, I get an IO Error. I was informed that I would have to create a Web Application instead of the Web Site as the web application would give me the default.aspx.designer.cs file for setting the FileUpload control as Public to be used in the upload.ashx file. But after doing that it basically breaks the code. What works in the Web Site, does not seem to want to work in the Web Application. What I would like from the .NET community is some help in making the Uploadify script to create Thumbnails. The script for the Thumbnails that I am using (or trying to use) is here

- In have a website where users can upload their photo and along with their profile.- I store the photo as binary data in database.- Using ASP.NET MVC 2.0 FileContent option, I display Photo back in the browser, when user view his/her profile detailsQuestion: Currently I am showing image as-is and not restricting width/height, so that users see exactly whatever image they uploaded as-is without distortion. However I want to do like every other website: Show only smaller image alwayswith fixed size and allow user to click on it to pop-up and show original image as-is in pop-up.NOTE: I can do this simply restricting width and height to fixed limits but still show original image. But in this case image is distorted as it was not originally designed for this dimension.This very basic question and I am seeing many options, including some libraries. But don't know what is best way to do this using ASP.NET MVC 2.0
View 1 RepliesI have a website that enable the user to upload pics to server (uploaded pics sizes are 300x400 and approximately 270kb). In my app. I am having another page that lists the pics and I am using there an image control for that purpose. The Image control sizes are 80px width, 60px height. My question is how can I improve the download speed by minimizing the images ? Do I have to create a thumbnail for each picture the user upload?

View 3 RepliesI was discussing load-balancing with a colleague at lunch. I admit that I know very little about this topic. We were discussing the various ways of maintaing session in a ASP.NET application -- none of which suited the high performance load balancing that he was looking for. What about Silverlight? says I. As far as I know it is stateless, you've got the app running in the browser and you've got services on the server that feed/process data. Does Silverlight totally negate the need for Session state management? Is it more friendly to load-balancing? Is it something in between?
View 3 RepliesWe have three web servers in our web farm that are load balanced using the Network Load Balancing Manager in Windows 2003. The sites that run on these boxes use In-Proc ASP.NET session. Our assumption is that the balancing uses a "sticky" session because users seem to be assigned to a given server during their use of the application as well as there doesn't appear to be any session error where the session data is residing on a previous machine. My question is how can I 1) verify that our balancing configuration is using "sticky" sessions and 2) can someone explain the load balancing feature in Windows 2003 relative to ASP.NET web applications?
View 1 RepliesIs there any solutions that "increases power of a single machine" instead of traffic distribution between different hosts. I mean the following schema: "Central server" receives all requests and for its execution it provide "a copy of shared memory" to different hosts.

View 8 RepliesI wanted to understand the behavior of HttpContext.Current.Application during the load balancing. I have read that session can be stored in disk hence can be retrieved from different servers. Is this true for HttpContext.Current.Application also. Does the keydata stored in one machine is accessible in other different machine too?
View 1 RepliesI am new to asp.net, I have been tasked to upgrade the physical architecture to load balancing environment to support the application. I done some reading the session state should be configure to Out-Process instead of In-Proc to support load balancing. Is there any other issues I need to take note for asp.net web application to run in the load balanced environment?
View 1 RepliesMy website/application is in ASP.NET. I use the traditional Session object when people connect so they have their preference, etc. My problem is that sessions were lost very often. I discovered that my hosting company was using load balancing on their servers, so one request on my website can be on one server, and the other on another one.
I tried to store the session data in a SQL Server database, but I quickly discovered that I can't create the needed database on my shared server because I only have one database in my package. Also, there is no guarantee that the rest of the script would have been able to run.
My questions: is there any other way to get around this problem? Should I buy another database only for this? Is there another type of session that I could use? Is there anything else I can use instead of session to keep track of my user when they are connected on my website?

View 1 RepliesI want to configure ASP.NET Website Project using WCF Service[NetTcp] (both in c#) for web-farm (for website) and NLB Load balancing (for service). I would like to configure following options for same.
NetTcpBinding.maxConcurrentCalls, NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections
Note: During single machine configuration when I changed value of NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections in WCF Service project to more that 10, which is default value. I got exception. When I changed this value in Website it was working fine. Due to this I had to keep in default configuration. Not sure why this is the case. Following reference gives idea how to configure in given environment but does not tell how to go about it. Ref: [URL] Update: Let me simplify a bit. Lets say I have following configuration.
2 IIS servers in Web Farm.
3 WCF Service Servers (NetTcp) in NLB
Default config. for single instance.
NetTcpBinding.ListenBacklog: 10
NetTcpBinding.MaxConnections: 10
NetTcpBinding.maxConcurrentCalls: 16
Now what will be my configuration setting in this environment. Will it be same as above or will be as follows.
NetTcpBinding.ListenBacklog: 30 (10*3)
NetTcpBinding.MaxConnections: 30 (10*3)
NetTcpBinding.maxConcurrentCalls: 48 (16*3)
I've been assigned a task to get a site ready for migration over to a load balanced architecture. It will have 4 active servers and 2 static, where the active ones will contain the main site, with the static ones containing images, text files etc..My question is, what is the best way to deal with the image paths in this situation?e.g. one one server the image will be something like : 'serverONE/images/image.jpg' but this need the ability to change to 'serverTWO/images/image.jpg'
