  Server variables for bit rate throttling Reply Contact Does anyone have a definitive list of the server variables that are available to programmatically control bit rate throttling? This page: http://learn.iis.net/page.aspx/149/bit-rate-throttling-extensibility-walkthrough/ Defines the following: ResponseThrottler-Enabled ResponseThrottler-InitialSendSize ResponseThrottler-Rate ResponseThrottler-FileExtension ResponseThrottler-EncodedBitRateKbps ResponseThrottler-ThrottleRatePercentage ResponseThrottler-InitialBufferTimeSeconds But it seems like that list may have been generated before the module was merged into IIS Media Services 2.0.  Is it still correct and complete? It looks like numeric values should be set as strings.  Is that correct?  Should they be integers, or are floats allowed? How late in the request lifecycle can these values be set? Are there any server variables to allow control over site-wide bandwidth?  If not, is it possible to change that setting programmatically? Is it possible to query the bit rate throttling module to determine the current load in some way?  Perhaps using performance counters?

Yes they are still correct and complete. It looks like numeric values should be set as strings.  Is that correct?  Should they be integers, or are floats allowed? They can only be strings.  How late in the request lifecycle can these values be set? They must be set before request notification RQ_SEND_RESPONSE. Are there any server variables to allow control over site-wide bandwidth?  If not, is it possible to change that setting programmatically? There are no server variables for that purpose, but you can do it via IIS configuration by setting the "maxBandwidth" attribute of the "limits" configuration element under the particular site.  You can do it programmatically through either AppCmd.exe or the ahadmin interface.  See below http://blogs.iis.net/ksingla/archive/2007/02/25/using-ahadmin-to-read-write-iis-configuration-part-1.aspx       Is it possible to query the bit rate throttling module to determine the current load in some way?  Perhaps using performance counters? There are no Bit Rate Throttling specific performance counters, but you may be able to achieve what you want using those under \Web Service.
