Limiting the maximum generated URL segment length

The maximum URL size is generally limited to about 2k characters due to Internet Explorer: See https://support.microsoft.com/kb/208427/EN-US. Nginx doesn't apepar to have a limit here but Apache servers by default impose a further limitation of about 250 characters per URL segment (text between slashes). When running under Apache PageSpeed circumvents this limitation, but if you employ proxy servers in your path you may need to re-impose it by overriding the setting here. The default setting is 1024.

pagespeed MaxSegmentLength 250

Apache:

ModPagespeedMaxSegmentLength 250

Nginx:

pagespeed MaxSegmentLength 250;
