We are looking for a developer to write a custom Web filter to use with Microsoft ISA Server 2004 (<[login to view URL]>). All of the samples in the SDK that comes with ISA are in C++. We would prefer this filter be written in C#, so that our C# developers can modify later on if needed.
The filter must be able to read a request's HTTP headers, compare the "user-agent" header and redirect the request based on the value found in the header. The value of the http header must be compared against an XML data file or a database. We will provide the code and algorithm to lookup from the source and do the comparison.
There will be 2 types of groups. Those requests that match the predefined criteria via the HTTP header I specified above, and those that dont. Those requests that dont, should be transferred to the destination server via a Web Publishing rule. Those that dont, will be transferred to an upstream ISA server for processing by that server.
This is all the info I will post here. Those interested can e-mail me at johnny_dev [at] [login to view URL] for more details.
**Knowledge Required
**To be able to write this, you have to be familiar with how ISA Server works. You must understand what a Web Publishing Rule is as well as a Server Publishing Rule. All of this is easy to learn if you are up for it.
Microsoft provides a trial of ISA Server 2004 which can be used for developing and testing this filter. Here is the URL: <[login to view URL]>
