Microsoft IIS

Some versions of Microsoft IIS will block requests with long URLS.

This will break some features of webtrees, including all the tables that load their content dynamically.

You can change this setting using a command similar to this:

%windir%\system32\inetsrv\appcmd set config "Default Web Site" /section:requestFiltering /requestLimits.maxQueryString:20480 /requestLimits.maxUrl:20480

Use these commands to restart IIS:

net stop w3svc
net start w3svc
