The following values are used to fine tune communication, performance, and proxy interaction when using the HTTP transport for streaming in App-V 4.6 environments. All of these values are located in the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\ Client\Network\Http or

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\ Client\Network\Http

Value
Type
Default
   
Applied
Description
StreamBufferSize
REG_DWORD
1048576
In bytes
This value determines the buffer size used to handle data requests. If the request size is larger than StreamBufferSize, the request is broken into multiple requests where the maximum data size requested will be less than or equal to the StreamBufferSize. If the StreamBufferSize value is 0, all of the data will be retrieved in a single request. Requires a restart of the App-V client service.
ResolveTimeout
REG_DWORD
30000
In milliseconds
This value is used by WinHttp for name resolution. If the resolution takes longer than this timeout value, the action is canceled. This is only for HTTP streaming. Requires a restart of the App-V client service.
ConnectTimeout             
REG_DWORD 
30000
In milliseconds
 
This value is used by WinHttp for server connection requests. If a connection request takes longer than this timeout value, the request is canceled. Requires a restart of the App-V client service.         
SendTimeout    
REG_DWORD 
300
In milliseconds
This value is used by WinHttp for sending requests. If sending a request takes longer than this timeout value, the send request is canceled.          Requires a restart of the App-V client service.         
ReceiveTimeout
REG_DWORD 
30000
In milliseconds
This value is used by WinHttp to receive a response to a request. If a response takes longer than this timeout value, the receive request is canceled. Requires a restart of the App-V client service.         
ForceProxyAutoDetect
REG_DWORD 
0
0-1
When this value is set to 1, it forces auto proxy detection instead of using IE proxy settings. Requires a restart of the App-V client service.         
ConcurrentRequests
REG_DWORD 
4
1-infinite
If the value is greater than 1, divides the Http streaming request into concurrent sub-requests for parallel streaming. Value must be greater than zero. Recommended setting is 4 (default).  Requires a restart of the App-V client service. 
SkipProxyDetection
REG_DWORD 
0
0 or 1
If the value is set to 1, App-V will not use IE proxy configuration. If 1, it overrides ForceProxyAutoDetect flag. Requires a restart of the App-V client service.         
FailedProxyAutoDetectRetryTimeout
REG_DWORD 
60       
varies
Don’t try auto-proxy-detection if it failed in last ‘x’ seconds for the current user. Where ‘x’ is the value of this flag. Requires a restart of the App-V client service.         
ProxyCacheLife
REG_DWORD 
60         
varies
The number of seconds the http proxy info is cached by App-V in memory for a user       Requires a restart of the App-V client service.
