+# Multi-Threaded Java HTTP Server
+
+This project contain two types of multi-threaded web servers, both equipped with thread-pooling capabilities, designed to efficiently execute a variety of simple tasks.
+
+
+## Project Structure
+
+- **Handler**: Manages incoming HTTP requests and routes them to the appropriate task.
+- **Tasks**: Defines individual tasks, each implementing a generic task interface for consistent handling.
+- **TaskExecutor**: Executes the specified task by dynamically instantiating it and processing the input.
+
+
+
+## Usage
+
+1. **Start the Server**: Compile and run the main server file to start listening for HTTP requests.
+2. **Make Requests**:
+   - **GET Request**: Retrieves a list of completed tasks.
+   - **POST Request**: Sends a task request with parameters. Example using `curl`:
+     ```bash
+     curl -X POST http://localhost:8000/ -d "TaskSimulateDownload&5000"
+     ```
+   - Replace `TaskSimulateDownload&5000` with the desired task and input.
+
+## the new  Tasks
+
+- **TaskGeometricalMean**: Calculate the Geometrical Mean : Geo-Mean=(a_1*a_2*…*a_n  )^(1/n)=√(n&a_1*a_2* ..*a_n ).
+- **TaskPrimeNumberFinder**: Finds prime numbers up to a specified limit.
+
+
+## Requirements
+
+- **Java 8** or higher
+- **curl** (for command-line requests)
+- **K6** (for test parallel requests)
+
+## Testing
+
+You can test the server's performance and concurrency with the tool **K6**. by running the follwoing commands on the K6TestScripts folder 
+
+``` bash
+k6 run testParallelTasks.js
+```
+
+``` bash
+k6 run testHeavyTask.js
+```
+
+``` bash
+k6 run testSingleTaskResponse.js
+```
