We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
If a file is larger than 128 KB and has the .map extension, you may receive one or more of the following error messages in the browser:
The ".map" extension is reserved and intended for association with server-side image maps in Internet Information Server (IIS) and Internet Information Services (IIS). The size of these image maps is restricted to 128 KB. IIS enforces this size limit on all files that have a file name extension of .map before it loads the files.
This behavior is by design.
To work around this problem, use image maps that are smaller than 128 KB.
Other ASCII files that are larger than 128 KB are not affected. If you have a file with another extension (for example, "a01"), and the file larger than 128 KB, you will not have problems changing the mime type or viewing the file in the browser.
