How to send a file to ICAP server for testing the functionalities using the powershell script?

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()
