Limits on redirect length

Are there limits on redirect URL length when using the AJP connector?

I can see response header length limits in the http connector but not an equivalent for ajp.

I'm getting the following errors in the catalina log and I *think* these are being triggered by a redirect to a URL with an 
excessively long get-parameter
