Attachment size: Is there a way to raise
the attachment size limit on the web form?
We find 200kb too small.
By default the IIS web server restricts
the size of ASP requests and file uploads,
so that for example IIS 6 (Windows Server
2003) has a limit of 200 kb. This is possible
Please follow the instructions below.
For IIS 6:
- Go to IIS and right click the
server, select Properties, and check
the box "Allow changes to MetaBase
configuration while IIS is running".
If after this step the metabase
file is still locked, try turning
off IIS or even restarting the machine
in safe mode.
- Open in a text editor the Metabase
file, which can be found at
- The variable AspMaxRequestEntityAllowed
limits the number of bytes in the
page request (by default 200KB);
change the value to 1073741824 (unlimited)
or to a limit of your choice.
- Check whether the same variable
shows up in other places in the
file and change them too.
For IIS 7:
- Highlight your website, then
open the "Advanced Settings..."
link in the right-most panel. Set
"ConnectionTime-out (seconds)" to
a much bigger number. For example:
"3600", which is an hour. Close
- While still highlighting your
website, click on the "ASP" tab,
then expand "Limits Properties"
and set "Maximum Requesting Entity
Body Limit" to 1073741824.
- Finally, open a command window
as an administrator and run the
set config -section:requestFiltering
This tells IIS the largest amount
you may upload, in this case, it's
100MB. You may set your number accordingly.
