Registry DataBase : Active Server Pages |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : AllowSessionState System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : Controls whether Active
Server Pages can create a session state in
applications. 0 : Session state is not allowed. The cookie ASPSessionID will not be sent to clients accessing the website and any attempt at storing in the session or at using Session_OnStart or Session_OnEnd generates an error. 1 : ASP scripts may allow a session state for all user accessing an .asp file on the website. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : BufferingOn System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : Controls caching by ASP
of output towards browser. 1 : All outputs are gathered before any of them is sent to the browser. Thus, HTTP headers can be defined anywhere in the script. The method Response.Buffer can be used to neutralize the effect of this default parameter. Rebooting is not necessary for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : DefaultScriptLanguage System : NT, 2K Type : REG_SZ Default value : VBScript |
ASP : Scripting language used as main
scripting language for all Active Server Pages
applications. The main scripting language can be used
between Active Server Pages delimitators (<%
et %>). The command <%@ LANGUAGE =
ScriptingLanguage %> can be used to neutralize the
effect of this default parameter. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : EnableParentPaths System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : Controls whether paths relative
to the current path can be used (i.e. with ..)
in Active Server Pages. 0 (False) : Prevents accessing files outside the server's virtual root path. 1 (True) : Allows accessing files outside the server's virtual root path. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : LogErrorRequests System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : Controls logging by the web
server of unsuccessful client queries in Windows NT's
Event Watcher. 0 : Disables logging. Rebooting is not necessary for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : MemFreeFactor System : NT, 2K Type : REG_DWORD Range : 50 to 100 Default value : 50 |
ASP : Maximum length of available
memory list in percentage of used memory list. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : MinUsedBlocks System : NT, 2K Type : REG_DWORD Range : 5 to 20 Default value : 10 |
ASP : Minimum length of used memory
list before items can be freed. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : NumInitialThreads System : NT, 2K Type : REG_DWORD Range : 5 to 20 Default value : 10 |
ASP : Number of working threads
created at Active Server Pages startup. If this
value exceeds the maximum possible number of threads, as
in ProcessorThreadMax, Active Server
Pages will use ProcessorThreadMax instead of NuminitialThreads. The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ProcessorThreadMax System : NT, 2K Type : REG_DWORD Range : 1 to 0x000000C8 Default value : 10 |
ASP : Maximum number of threads to be
created for each processor. Avoid more than 20 threads
for each processor. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : RequestQueueMax System : NT, 2K Type : REG_DWORD Range : 1 to 0xFFFFFFFF Default value : 500 |
ASP : Maximum number of .asp
query files to be stored in the query queue available for
each thread. If the maximum is reached, the value is sent
to clients from the registry value ServerTooBusy. The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ScriptEngineCacheMax System : NT, 2K Type : REG_DWORD Range : 1 to 0xFFFFFFFF Default value : 30 |
ASP : Maximum number of ActiveX
motor languages to be cached and stored in memory by Active
Server Pages. The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ScriptErrorMessage System : NT, 2K Type : REG_SZ Default value : The server encountered an error while treating the URL. Please contact your system administrator. |
ASP : This message will be displayed
in a browser if ScriptErrorsSentToBrowser is set to False. The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ScriptErrorsSentToBrowser System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : 1 : The web server writes debugging specifications (file name, error numbers and lines, description) into the browser in addition to writing this information in the log. Rebooting is not necessary for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ScriptFileCacheSize System : NT, 2K Type : REG_DWORD Range : -1, 0 to 0xFFFFFFFF Default : -1 |
ASP : Amount of bytes to be pooled
for caching precompiled scripting files, which enhances
the performances of Active Server Pages. 0 : Scripting files will not be cached. Performances may be poor if caching is not used. Sites with a lot of file traffic can increase this amount if the system has enough memory. 1 : All requested scripting files will be cached. The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ScriptFileCacheTTL System : NT, 2K Type : REG_DWORD Range : 0 to 0xFFFFFFFF Default value : 300 (seconds in decimal value) |
ASP : Time interval during which
scripting files will stay in the cache before being
gradually eliminated, if they have not been referred to. If the number of data files is limited or if clients only access a few files, increasing this value may enhance performances. 0xFFFFFFFF : Files will stay in cache undefinitely. The server needs rebooting for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : ScriptTimeout System : NT, 2K Type : REG_DWORD Range : -1, 0 to 0xFFFFFFFF Default value : 90 (seconds in decimal value) |
ASP : Time for thorough execution of
a script allowed by Active Server Pages. If the
script is not ended during this period, the server ends
it and writes an event in the event log. To prevent that,
use a script calling the method Server.ScriptTimeout. -1 : Special value allowing scripts indefinitely. Rebooting is not necessary for changes to be effective. |
Key : HKLM \SYSTEM
\CurrentControlSet \Services \W3SVC \ASP \Parameters Entry : SessionTimeout System : NT, 2K Type : REG_DWORD Range : 0 to 0xFFFFFFFF Default value : 20 (minutes in decimal value) |
ASP : Default time interval during
which a Session object must be available once the
last query associated with that object has been made. To
prevent that, use a script calling the method Server.ScriptTimeout. Rebooting is not necessary for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : StartConnectionPool System : NT, 2K Type : REG_DWORD Range : 0 or 1 Default value : 1 |
ASP : 0 : Disables the concentration of ODBC connections The server needs rebooting for changes to be effective. |
Key : HKLM
\SYSTEM \CurrentControlSet \Services \W3SVC \ASP
\Parameters Entry : ThreadCreationThreshold System : NT, 2K Type : REG_DWORD Range : 1 to 0xFFFFFFFF Default value : 5 |
ASP : Number of queries which can be
dealt with in the common queue (i.e. queries which need
not being executed on a special thread) for Active
Server Pages. If the number of queries in the common
queue exceeds ThreadCreationThreshold, a new
thread is created in the group of existing threads (i.e.
the total amount of threads created by ASP to
treat incoming queries), but only if the number of
threads in the group is less than the maximum indicated
for ProcessorThreadMax. The server needs rebooting for changes to be effective. |
