📋 Tips & Best Practices
1.	File Permissions: Ensure that files in the current directory have the correct read permissions.
2.	Port Availability: Make sure port 8080 is not in use by another application.
3.	Security:
o	Avoid exposing sensitive information in server responses.
o	Regularly update the list of sensitive words.
o	Use TLS encryption to secure client-server communication.
4.	Logging: Check the server.log file to analyze requests. This log is helpful for debugging and tracking client activity.
5.	AI API Integration:
o	To connect to OpenAI’s API, use libcurl in C to make requests to https://api.openai.com/v1/.
o	Modify the /ai/message response to use the API-generated text instead of the hardcoded HTML response.

💡 How to Customize
Customization	How to Do It
Add AI Cloud API	Use libcurl to call OpenAI API and modify the /ai/message route.
Add Custom Endpoints	Add new paths in the accept_request function, like /ai/summary.
Change Sensitive Words	Update the sensitive_words array to add/remove terms.
Change the Port	Update the port in the PORT constant.
Log Customization	Change the log_request function to log more data (user-agent, request method, etc.).

🛠️ Example Logs
Here’s an example of server.log after running the server for a few minutes:
[2024-12-11 12:34:56] Client: 192.168.1.2 Requested: /index.html
[2024-12-11 12:35:01] Client: 192.168.1.3 Requested: /ai/message
[2024-12-11 12:35:15] Client: 192.168.1.2 Requested: /private/passwords.txt (BLOCKED)
These logs allow you to see which clients connected, what they requested, and whether their access was blocked.

🌐 API Integration Example
Here’s a basic way to integrate the OpenAI API for generating dynamic responses.
1.	Use the libcurl library in C.
2.	Replace the /ai/message response with a call to the OpenAI API.
Example Code for Calling OpenAI API
#include <curl/curl.h>

void ai_message(int client) {
    CURL *curl = curl_easy_init();
    if (curl) {
        const char *url = "https://api.openai.com/v1/chat/completions";
        const char *auth_header = "Authorization: Bearer YOUR_OPENAI_API_KEY";
        const char *post_data = "{\"prompt\":\"Hello AI!\", \"max_tokens\":50}";

        curl_easy_setopt(curl, CURLOPT_URL, url);
        curl_easy_setopt(curl, CURLOPT_POST, 1L);
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, post_data);
        
        struct curl_slist *headers = NULL;
        headers = curl_slist_append(headers, "Content-Type: application/json");
        headers = curl_slist_append(headers, auth_header);
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
        
        CURLcode res = curl_easy_perform(curl);
        if (res != CURLE_OK) {
            fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
        }
        curl_easy_cleanup(curl);
    }
}
Steps to Use This API Call
1.	Replace YOUR_OPENAI_API_KEY with your OpenAI API key.
2.	Compile the program with libcurl:
gcc -o ai_server ai_server.c -lpthread -lcurl
