Image Upload works but...

[kliz0328]

I am using this code to upload an image

inpFileUp.PostedFile.SaveAs(path)

and am using the HTMLInputFile Control to do so. The image uploads fine, but when the page redisplays the picture is still the old one, unless I refresh the page then it changes. Do I need to call some type of Dispose() method with the save as code above?

The browser is probably serving a cached image. You could either disable caching on th page or append a random id to the end of the image name to fool the browser into thinking it is a different image and therefore request a new image on each load of the page.

Is this what I would use to disable the cache? Sorry I am not at work right now so I can't test it.

Response.Expires = 0

Yes, there are several methods but I believe that will work.

what is the best method for this in your opinion?

I'd probably use a random id on the image but why don't you just try them and see what you prefer...

Another option is just to save with a different file name and reset the link to that file. That way you don't run into cache problem when you want to change the file, but you'll get the performance benefits of caching when you want them.
