Have you installed the URL Rewrite module? Or the Request Filtering module?
If so, remove them. By the way, the URL below is 360 ASCII characters. Not 288. No clue where you get 288. -----Original Message----- From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Nelligan, Steven M Sent: Wednesday, April 5, 2017 12:37 PM To: ntsysadm@lists.myitforum.com Subject: [NTSysADM] Question about IIS I have not done networks nor any IIS configuration for over a decade. I've been doing development. I am having a problem with having an IIS front end to Tomcat in order the use the Computer Associates SiteMinder. (requirement) In production we have SiteMinder talking directly to Tomcat and this has worked for several years with no problem; but due to pricing issues we need to move to the SiteMinder version which talks to IIS. We are running Windows 2008r2 and using IIS 7.5 on the server. IIS is running port 80 and 443 and redirecting these to port 8080 and 8443. The problem is we are getting error 400 on long urls. Sample URL: https://xxxxx.xx.xxxxxxxx.xxx/fsportal/portal/_ns:Z2NwcmVxMV9fY3ByZXEyfGMwfGQxfGkvY3ByZXF1ZXN0Lz93aWNrZXQ6aW50ZXJmYWNlPTowOndpemFyZDpmb3JtOnZpZXc6c3RlcDIuZGV0YWlsLnBhbmVsOmNmb2FwYWwuZW50cnk6Y2ZvYXBhbC5mb3JtOmNoYXJ0VGV4dEZpZWxkOjpJQmVoYXZpb3JMaXN0ZW5lcjozOnxqX3d1dmlldz0xPS9jcHJlcXVlc3QvP3dpY2tldDppbnRlcmZhY2VcXD06MDo6Ojp8Zg__/carpool?random=0.292144144791900 The above URL is 288 Characters and returns 400 status error from IIS. If we randomly delete 18 of these characters, IIS forwards the URL. NOTE: the two apparent spaces in the URL above are actually underscores. Following are the changes we made to attempt to override the IIS default of 260 characters. These are the changes that were made today in testing that did not resolve the issue. Changed maxUrlLength = "1000" in IIS Configuration Editor at sites & root levels Changed relaxedUrlToFileSystemMapping = "true" in IIS Configuration Editor at sites & root levels Changed maxUrlLength = "1000" in web.config Changed relaxedUrlToFileSystemMapping = "true" in web.config Changed UrlSegmentMaxLength = "1000" in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters Any IIS experts out there which could let me know what I need to do to get this to work with IIS?
