View 4 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 4 RepliesAssume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.

View 1 RepliesI'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

View 2 RepliesI've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.

I wanted to combine app_themes css files into one on the fly. I did so using Mads Cristensen technique. But now all elements that has background image defined through css (see picture) don't display image. I believe that is because css files are not relatively referenced anymore (../), but through axd file. I'm trying to fix this by changing reference to image files without success. I already tried background: url("~/App_Themes/44/images/myimage.gif") and this works for pages that combined css. But the problem is that there are other pages in this project that don't use this css combining and now they lost reference to background images.

View 2 RepliesI'm using ASP.NET 4 Web forms routing, for example like this:
routes.MapPageRoute("page-browse", "{Language}/{Label}", "~/Default.aspx")
So the webadress could look like: http://localhost/mywebsite/eng/home
In the root of my website I have a folder "Images".
Image display works when I'm in the root of my website, e.g. by using http://localhost/mywebsite/default.aspx
But when using routing it doesn't work, because the image relative url will look at http://localhost/mywebsite/eng/images instead of http://localhost/mywebsite/images
Is there a way to prevent this using ASP.NET 4 Routing mechanism? Or is the only way to use absolute url's to images?

View 2 RepliesI'm trying to get add a link to a DNN usercontrol where when the user clicks it they can download a particular PDF. The code in my link click event is:
Response.ContentType = "Application/pdf";
Response.AppendHeader("Content-Disposition", string.Format("attachment; filename="" + "fileName" + """));
Response.BinaryWrite(Content);
Response.End();
When the link is click though the code runs through with no apparent exceptions but the dialog is never displayed. Similiar code to this has worked for me in non DNN applications and worked fine.
