SUMMARY

Neither static nor dynamic compression works if the URL contains a slash as part of the parameters passed to the executing DLL file. You can confirm that the file is not being compressed because it is not in the Internet Information Services (IIS) compressed folder. By default, the compressed folder is located at:

%WINNT%\IIS Temporary Compressed Files
