=========================================
Configuration:
On NT XP and 2003 platforms, the system account should inetinfo the program should be running with IIS5 in a coexistence mode filter. So the system account should be given to all the Isapi-rewirite DLLS and all the httpd. INI file with at least Read permission, we also recommend to give the system account for all including httpd. INI file's folder, which will allow HTTP to be generated. PARSE. Errors files that contain configuration file syntax errors. Additional permissions are required for the proxy module because it will run in connection pooling or high-isplated application mode, and the IIS account sharing pool and high-isolation pool should be given to Rwhelpere. The Read permission for the DLL. By default iwam-"computer name" is used in all pools, and a pool account should be established in the corresponding COM + application settings with the help of Com+administration MMC snap-in
Configuration file Format:
There are two forms of configuration Files-global (server-level) and individual (site-leval) files, The global configuration file should be named Httpd.ini and appear in the Isapi-rewrite installation directory, and the file's shortcuts are provided through the Start menu, and the individual configuration file should be named httpd. INI and can appear in the physical root directory of the virtual site, the two types of formatting are the same and are standard Windows. INI file, all instructions should be placed in this section and all instructions should be placed with a divider line, any text other than this will be ignored

# Some Custom Rules
Rewritecond Host: (. +)
Rewritecond directives
Syntax: (syntactic) Rewritecond testverb Condpattern [Flags]
This instruction defines a conditional rule that pretesting the rewritecond instruction before the rewriterule or Rewriteheader or rewriteproxy instruction, followed by its only pattern matching the current state of the URI and the additional conditions applied.
Testverb
Specifies verb that would be matched against regular expression.
Specifically defined verbs match the specified expression
testverb= (URL | Method | VERSION | Httpheadername: | %servervariable) Where:
Url-returns Request-uri of client Request as described in RFC 2068 (HTTP 1.1);
Returns the Request-uri of the requirements described by the client in RFC2068
Method-returns HTTP method of the client request (OPTIONS, GET, head, POST, put, DELETE or TRACE);
Returns HTTP methods for client requirements (OPTIONS, get, head, POST, put, DELETE or TRACE)
Version-returns HTTP version;
Return HTTP version
Httpheadername-returns value of the specified HTTP header. Httpheadername can is any valid HTTP header name. Header names should include the trailing colon ":". If specified header does not exists in a client's request Testverb is treated as empty string.
Returns the value of a defined HTTP header file

ServerVariable returns the value of a defined server variable. For example, the server port, the list of all server variables should be established in the IIS document, variable name to apply the% character reservation;
Condpattern
The regular expression to match Testverb
Regular expression Matching Testverb
[Flags]
The flags is a comma-separated list of the following flags:
O (normalize)
normalizes string before processing. Normalization includes removing of a url-encoding, illegal characters, etc. This flag are useful with URLs and url-encoded headers
Rewriterule directives
Syntax:rewriterule pattern formatstring [Flags]
This instruction can occur more than once, and each instruction defines a separate rewrite rule, which is important because the command is useful for applying runtime rules
