Auto refresh Image
Hello,
I am using an ASP script which reads the contents of a folder with image files and outputs its content to the client. I am trying to make it auto refresh but it only works if the refresh is requested from the browser. I have added the following content, but does not work. Since the client is getting a HTML response, I have added a refresh meta tag (<META HTTP-EQUIV=refresh CONTENT=10;URL=http://webphone.nsgtmo.com/photopage.asp>) which seems to reload the page but does not re-run the code.
Response.Expires = -1
REsponse.ExpiresAbsolute = Now() -2
Response.AddHeader "Pragma", "no-cache"
Response.AddHeader "cache-control","Private"
Response.CacheControl = "private"
Response.AddHeader "Refresh", "10;URL=http://webphone.nsgtmo.com/photopage.asp"

Yes, you are right. If I installed an add-on to the IE browser and set it up to reload the page it will reload it and display the updated images in the folder to the client. I added (found this on another problem) a javascript code <script>setTimeout('locati
That will only work if the image doesn't have an expiration value set in the header. If it does the refresh will NOT download a new image.
Let me know how this helps or if you have a question.
