Setting Request Limit on IIS7

We had a client trying to upload a 44mb file, and it was failing.  The ColdFusion page that that did the upload had a very high timeout setting, so I didn't think that timeout was the issue.  The ColdFusion administrator had a request limit set of 100MB (which I believe is the default).  What was up? 

It took a bit of googling to realize that IIS7 (the webserver on our Windows 2008 Server), had a default request limit of 30MB.  The solution is rather simple.  With IIS7, a web.config file can be used to set a variety of webserver settings, so I added one to the site that was having the problem.  Here are the contents of the file:

<?xml version="1.0" encoding="UTF-8"?>
                <requestLimits maxAllowedContentLength="1024000000"/>

This sets the request size limit to 100MB, to bring it in line with ColdFusion.  This isn't the only thing that can be controlled with web.config.  For some information on how to tighten security on a site using web.config see this page:

  • Modern Signal significantly enhanced our site to be more efficient and user-friendly. They provide excellent customer service with timely and cost-effective solutions.

    - Center for Medicare Education

  • This was by far the smoothest website redevelopment I have ever experienced. Modern Signal was a wonderful company to work with and we greatly value our working relationship. 

    - National Association of Student Financial Aid Administrators

  • Modern Signal understands our business - from future needs to current limitations - so their solutions are always scalable, solid, and service-oriented.

    - National Association of Home Builders

  • Modern Signal has a professional staff that was very responsive to our needs during all phases - scoping, developing, implementing and maintaining - of our project.  We have been pleased with their ability to deliver quality work on time and on budget.

    - The National Center for Safe Routes to School

  • Modern Signal worked with us to understand our needs and figure out what solution would work best for us. Our Lighthouse CMS is perfectly suited to our website goals. When we later needed to modify the CMS, they again took the time to understand exactly what was  needed and then built that functionality rather than delivering a cookie cutter solution.

  • We wouldn’t have gotten where we are today without your support over the years.  Modern Signal has always been a great partner to us.
