Who was not faced to the error 404 page in SharePoint 2007 ?
Specially when the End User explain that his site is no more working?
Little debug, shows that the EU had the wonderfull idea to create a new folder for his documents (or a document) containing a special caracter : "+" sign.
The workaround that I found, was to rename the folder/file, and ask the EU not to use anymore those special caracters.
Yesterday, I had a post from Fabrice Romelard's blog explaning how to solve this issue, and the root cause of this issue : IIS 7.0 replace the + sign by a space in the URL, but shows the correct URL in your navigator.
The solution is to add into each Web.Config field of each SharePoint Web App, this line :
<requestFiltering allowDoubleEscaping="true" />
Then, I was faced to another problem : where to add this command when the "requestFiltering" is already used for the "requestLimits maxAllowedContentLength" command.
Simply write the section like this :
<system.webServer>
<security>
<requestFiltering allowDoubleEscaping="true">
<requestLimits maxAllowedContentLength="524288000" />
</requestFiltering>
</security>
</system.webServer>
Hope it'll help, as all found exemple on internet shows all commands one by one, but not in the same Web.Config
That's all folks
