Create a powershell script with the content below and save it as icap_win.ps1

TEXT
    
​x
 
param (
    [string]$icapServer = "127.0.0.1",  #ICAP server IP
    [int]$icapPort ="1344",                     # ICAP default port
    [string]$icapService = "/OMSScanReq-AV",          # ICAP service name
    [string]$filePath = ""  # Path to the file
)
​
# Read file content
$fileContent = [System.IO.File]::ReadAllBytes($filePath)
$fileSize = $fileContent.Length
$chunkSize = [Convert]::ToString($fileSize, 16)  # Convert size to hexadecimal
​
# Define ICAP Headers
$icapRequest = "REQMOD icap://$icapServer`:$icapPort$icapService ICAP/1.0`r`n"
$icapRequest += "Host: $icapServer`r`n"
$icapRequest += "User-Agent: PowerShell-ICAP-Client`r`n"
$icapRequest += "Encapsulated: req-hdr=0, req-body=" + ($fileSize + 4) + "`r`n`r`n"
​
# Define HTTP Encapsulation (Required by ICAP)
$httpRequest = "POST /test.html HTTP/1.1`r`n"
$httpRequest += "Host: example.com`r`n"
$httpRequest += "Content-Length: $fileSize`r`n"
$httpRequest += "Content-Type: application/octet-stream`r`n`r`n"
​
# Properly format file content as chunked encoding
$chunkedData = "$chunkSize`r`n"
$chunkedData += [System.Text.Encoding]::UTF8.GetString($fileContent) + "`r`n"
$chunkedData += "0`r`n`r`n"  # End of chunk
​
# Combine ICAP and HTTP requests
$fullRequest = $icapRequest + $httpRequest + $chunkedData
​
# Create a TCP socket to communicate with the ICAP server
$tcpClient = New-Object System.Net.Sockets.TcpClient($icapServer, $icapPort)
$stream = $tcpClient.GetStream()
$writer = New-Object System.IO.StreamWriter($stream)
$reader = New-Object System.IO.StreamReader($stream)
​
# Send the properly formatted ICAP request
$writer.Write($fullRequest)
$writer.Flush()
​
# Receive and display ICAP response
$response = $reader.ReadToEnd()
Write-Output "ICAP Server Response:`n$response"
​
# Close the connection
$writer.Close()
$reader.Close()
$stream.Close()
$tcpClient.Close()
Copy
