问题
I have implemented a small method
for my site where I upload an image. using a FileUpload control, I choose an image, and then when I hit a button, the UploadImage() method is generated.
The UploadImage() method stores the image in a folder in the server and stores its path in the Database. It also checks the file size of the image, if greater than a megabyte, an alert is displayed, else, the image is upload and stored. This has been tested with a few images ranging from 45KB to 900KB. It has worked perfectly.
THE PROBLEM:
When tested with a few images of approximately 4MB, sometimes it shows the 'error' since it is greater than 1MB, but at other times (I do not know why), Google Chrome directs me to a page telling me that the localhost has been interrupted.
When debugging, I do not even enter the button Upload click method! I find this very strange. The extension of the image doesn't seem to be the problem since I am testing with .jpg and .png.
Did some one experience the same problem? Is there a guru that can help me?
Thank you very much.
update:
it seems that files of 4052kb have worked correctly (i.e. an error message was displayed) but files over 4098kb) resulted in a local host interrupt. When the button is clicked, the browser below shows 'sending request' and uploading (0%) and displays "The connection to localhost was interrupted."

Please take a look at the maxRequestLength of the httpRuntime element of the web.config.

This is where you set the maximum request length. When it is exceeded, the runtime throws an exception. The default size is 4096KB.
