where external files / images are being loaded from. By this I mean that I'm aware that external JS files / Images are cached on the first load of a page. What I'd like to have is a tool that confirms to me that on subsequent requests these files are in fact being loaded from the users cache rather than downloading the file again.
View 3 RepliesWe are writing a portal and like every portal we store html data in Db fro Modules. So I thought that I can cache each module in files. I use OnLoad event to check if there is a cache file for this Module, use that and else create cache file:
if (!IsPostBack)
{
string Path = AppDomain.CurrentDomain.BaseDirectory + "CacheModules" + ModuleId + ".dat";
if (File.Exists(Path))

How to upload images with some conditions

Project: Asp.net 2, MSVS VB.net
Hoster: Windows, Shared environment
I ran firebug (via Firefox) with googles speed test, and I got two major issues come back to me, and I sent two questions to my hoster.
1) MY QUESTION TO THE HOSTER1: Css, Js image files loaded to browser and cache from my hoster go up the request process with out the lastmodified data, and thus the browser cache does not know when to refresh the files on expiration date?
MY HOSTER RESPONSE: LastModified is a script that can be implemented to your java coding (ME: I think hes confused here, I dont use java) which you need to enter yourself. It is not a server function that we can modify on our side but it is something that you will have to change your website coding.
2) MY QUESTION TO THE HOSTER2: Firebug results said that GZIP is not activated for my files of CSS, js and asp.net pages, why not?
MY HOSTER RESPONSE: Currently, you are using Windows environment hosting services which does not support gzip. gzip is available on our Linux environment hosting plans as gzip is mainly for Linux OS.
After falling off my chair, I have to ask, what can I do via coding on my asp.net2 vb.net project? I thought these two issues were purely server related and nothing to do with code with the project? What do I do, or is my hoster wrong ?
I am showing images of members on my website. The images are already saved to file. I want to add some text to the image that is loaded in the image control. I don't want to save it to file, just display the change on that web page. I have seen code on how to do this but I do not see how to load it into an image control. Is this possible without saving it to file?

View 2 RepliesMy requirement is that I have a few hyperlinks on a webpage and when the user clicks on these hyperlinks I should redirect the user to an asp.net web page(Default.aspx) in a different website.
For the 1st time when the user clicks on one of the hyperlinks it will launch a new browser window with the Default.aspx loaded and then if the user clicks on some other hyperlink I want to redirect the user to the existing browser window(in which deafult.aspx is already loaded)with the content related to this particular hyperlink loaded,instead of launching a new browser window/tab.
But I am not sure of how to achieve this.I wonder if I can add some js to the asp.net Default.aspx page to achieve this.
I'm using an outside page to update an image in my system. When I'm redirected back to the page I've worked in, I still see the old picture. I don't see my changes until I press ctrl+f5.

How can I retrieve file information (size of file) before it is uploaded to the webserver?
I would like to create a multi file upload. I have it working in JQuery but I would like to know the size of the files to set a limition by summing up the total the file sizes together.
I am using if (document.getElementById('<%= MainImg.ClientID %>').complete) {
hideLoadDiv();
}
to hide a div which indicates the image is not loaded yet,but it hides before the image has finished loading and is shown, while the browser is giving me a message that the page is still transferring data from the server :S
Is there another function I can use to make sure that the image is fully loaded?

View 2 Repliesi am using Jcrop to give users the option to crop there images, i have hit a small caching problem.
if you open an image which is already on the server and crop it. my jcrop works and crops the image fine but when i reload the image the old version is displayed. i have this inside an update panel.
so is there a way of removing the browsers cache before i reload the image?
Users can edit images downloaded from my site and then upload them back using a WCF Web Service. The problem is when users go to view images, they often do not see the latest versions because of caching. I'd rather not turn off the cache because it substantially reduces bandwidth. Is there a way to have the Web Service perform some action upon an upload to notify the next web client call that the image has changed?

View 1 Repliesi am making a Website with c# and ASP.NET 3.5, i just made an HttpModule to handle the NHibernate Session Life (Open and close).
I added it to the web.config and everything works fine. (all the query, code, etc working fine) except that CSS file of my masterpage is not loading !!
When a user visits our site they see a coverflow. They are not logged in so they cant see any images. Once they log in they should be able to see images in the coverflow but they cant because the flash object is being cached.
A user can get around this problem by setting the IE settings to (check for newer versions of stored pages every time they visit a site) however we need a way to force the browser to refresh the flash object once they are logged in, without telling all of our users to change the settings in their browser.
Is this possible?

On my webpage I am loading 30 .jpg Images and a .SWF(Flashfile) that takes 4 MB. The problem is that when the Page is loading in, this 4 MB flashfile is loading in together with the images wich makes it to take very long time.
What I would need to do, is to load the webpage with all its images First and when the webpage is loaded, now I will need to load this 4 MB flashfile in the background. When this file is loaded to memory, I will start playing that in a loop in this Flashcontrol that I have.
How is a scenario like this possible to do? I struggled with it before but couldn´t solve it.
