GIF File Not Updated in Internet Explorer 3.02 with Proxy Server (191801)



The information in this article applies to:

  • Microsoft Internet Explorer 3.02 for Windows NT 4.0
  • Microsoft Internet Explorer 3.02 for Windows 95

This article was previously published under Q191801

SYMPTOMS

When you are using Internet Explorer 3.02 with a proxy server, if you update image data in the files on your Web server, Internet Explorer may display only the cached data on the proxy server instead of the latest images. Specifically, this behavior may occur if you change image data content but do not change the image file name.

CAUSE

When you click Refresh in Internet Explorer, the browser sends an HTTP GET request for the Web page with a "pragma=no-cache" entry in the header. Additional GET requests for the image data are sent without the "pragma=no-cache" entry.

RESOLUTION

To work around this issue, disable the cache in the proxy server.

STATUS

Microsoft has confirmed this to be a problem in Internet Explorer 3.02 for Windows 95 and Windows NT 4.0.
