Description of bug: When using SSL and Client certificates any file over 50k uploaded with cffile crashes the coldfusion server. As long as you stay under 50k it runs fine. We turned off client certificates and successfully uploaded a 203mb file without an issue.

Comments: This is on Windows 2003/IIS6 using MX7

Fix/Work-Around   [Bobby Schuchert]   [Thursday, May 17, 2007 07:28 AM] It turns out that this really isn't a bug in ColdFusion, it seems to be a setting in IIS6 that needs to be changed. I did not find this fix, I found the post of the person who found the fix. The fix: " The issue of the 50kb limit and client certificates has to do with IIS 6 Metabase settings and the client certificate requiements: Use Metabase Explorer (included in IIS6 Resource Kit - iis60rkt.exe) to add the following entries to C:\WINDOWS\system32\inetsrv\Metabase.xml (Do not use MetaEdit – will not work with IIS6) w3svc/1/uploadreadaheadsize 800000000 (DWORD) w3svc/1/SSLAlwaysNegoClientCert 1 (DWORD) Metabase Explorer operates a lot like Regedit. • Open Metabase Explorer • Go to LM/W3SVC/1/ • Right click and choose New – DWORD Record • Choose uploadreadaheadsize from the pulldown • Once it’s added you can double-click it to change value (default is 49152) 48K Change it to a larger value. Then repeat the same steps above to add SSLAlwaysNegoClientCert and set that to 1 (True) Open C:\WINDOWS\system32\inetsrv\Metabase.xml with notepad and search for the above settings to confirm that they were added.
