request Management in Sharepoint 2013

There are hardware/ software load balancer used to route the request at a network level to web servers.            

But such configuration not fully solved the problem.

Now SP 2013 comes with this to route requests from application level. By this SharePoint can refuse or redirect HTTP requests individually within the farm to dedicated or different servers in the farm for specific workloads.

It can now recognize the origin of incoming requests like browsers, applications, IP to reduce the priority.

Request Management Rules:

These rules are applied per web applications which are disabled by default.

These rules are either throttling or routing rules.

Throttling rules evaluated before routing rules $ if request matches the criteria, the request is refused.

Throttling and routing rules use the following HTTP request header properties:

·         CustomHeader

·         Host

·         HttpMethod

·         IP

·         SoapAction

·         Url

·         UrlReferrer

·         UserAgent, such as a Microsoft Office OneNote client application

·         EndsWith

·         Equals

·         Regex

·         StartsWith

Creating & Managing Request Management:

No administrative user interface for Request Management. Only using powershell.

Create routing rules using powershell -

·         $webapp = Get-SPWebApplication “Web application URL”;

·         $rmsettings = Get-SPRequestManagementSettings $webapp;

·         $MachTargets = @("SP1");

·         $machpool_1 = Add-SPRoutingMachinePool -RequestManagementSettings $rmsettings ' -Name "Machine Pool 1" -MachineTargets $MachTargets;

·         $RMrulecriteria = New-SPRequestManagementRuleCriteria -Property Url '-MatchType Regex -Value ".*\.docx"

·         $DocRule = Add-SPRoutingRule -RequestManagementSettings $rmsettings -Name "DocRule" '-ExecutionGroup 0 -MachinePool $Machpool_1 -Criteria $RMruleCriteria
