SYMPTOMS
When Microsoft Internet Explorer makes many requests for objects, it may stop responding (hang). Requests to the current Web server may not be completed, and the Internet Explorer window displays an arrow-hourglass pointer.

When this problem occurs, images may not appear as expected, and a message may appear in the status bar at the bottom of the window that there are a certain number of &quot;items remaining&quot;, or it may say &quot;Done&quot;.

<div class="cause_section">

CAUSE
This problem may occur if Internet Explorer sends many HTTP requests, and then aborts many of those requests. When this problem occurs, HTTP requests to the same Web server do not succeed.

Note When you use other Web servers, HTTP requests work correctly.

<div class="moreinformation_section">

MORE INFORMATION
Typically, when Internet Explorer aborts an HTTP request, the page no longer has to have a reference for that resource (such as an image, a JScript (.js) file, an HTML component (.htc) file, or a Cascading Style Sheet (.css) file). This problem may occur when you rapidly open and close many nodes of a DHTML treeview-like control. The problem occurs more frequently when Internet Explorer is set to look for newer versions on every visit to the Web page because this generates more HTTP requests. (Typically, these requests are &quot;get&quot; requests).

Other factors that contribute to HTTP traffic may also generate more HTTP requests. These factors include setting the cache attribute and network latency. Network latency contributes to the problem because there is a greater chance of aborting an HTTP request.

If you raise the connection limit per server, you can delay the problem. The problem occurs because Internet Explorer may occasionally lose HTTP connections internally. Because 2 is the standard connection limit for HTTP 1.1, the problem occurs later if you raise the connection limit.
