SYMPTOMS
When you are using a form to request an ActiveX document, the server may not correctly request the document if the form uses the POST method, and the input parameters from the form include the required parameters to obtain the document.



CAUSE
This problem can occur because there are architectural changes in Internet Explorer 5.5 that allow Mshtml.dll to request Multipurpose Internet Mail Extensions (MIME) type and file cache information about the requested document from Urlmon.dll.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Internet Explorer 5.5 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:   Date      Time     Version        Size      File name     Platform --  3/14/2001 3:00pm   5.50.4615.1400 2,745,616 MSHTML.DLL    x86 3/14/2001 3:01pm  5.50.4615.1400 1,146,128 SHDOCVW.DLL   x86



WORKAROUND
To work around this problem, the author of the HTML page must change the method from POST to GET if the input data and the Uniform Resource Locator (URL) length is not greater then 2048 bytes.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
