I am trying to download html from website picnob.com, When I request using POSTMAN it gives full html. But when I do same with my c# code it gives “forbidden” error.
Below is postman code which I am using
var client = new RestClient("https://www.technilesh,picnob.com/");
var request = new RestRequest(Method.GET);
request.AddHeader("postman-token", "6bb5dfa4-6097-e628-8b6c-4dd814ac43");
request.AddHeader("cache-control", "no-cache");
IRestResponse response = client.Execute(request);
When I saw HTML if response it says “Enable JavaScript and cookies to continue”. How can I resolve this issue?

- Answer: To resolve the “forbidden” error when trying to download HTML from the website picnob.com using C# code, ensure that your code enables JavaScript and cookies in the request headers.
- Introduction: The problem at hand involves encountering a “forbidden” error when attempting to download HTML from the website picnob.com using C# code. This issue is crucial to address as it prevents successful data retrieval, potentially hindering critical processes that rely on this data.
- Want to know more? When making requests to the picnob.com website using POSTMAN, the full HTML is successfully received. However, when attempting the same with C# code, a “forbidden” error occurs. The HTML response advises enabling JavaScript and cookies to proceed. This discrepancy raises concerns about why the C# code is not receiving the full HTML content and how to resolve this issue.
- Now Here’s the Best Part: To address the “forbidden” error and retrieve the full HTML content successfully, consider the following potential solutions:
- Solution 1: Implementing User-Agent Header Set a User-Agent header in the C# code to mimic a browser request. This may trick the server into responding with the complete HTML content, just like POSTMAN.
var client = new RestClient("https://www.picnob.com/");
var request = new RestRequest(Method.GET);
request.AddHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36");
IRestResponse response = client.Execute(request);
- Solution 2: Handling Cookies in C# Code Ensure that the C# code includes appropriate cookie handling to support sessions on the website. This can be achieved using the CookieContainer class in C#.
var client = new RestClient("https://www.picnob.com/");
var request = new RestRequest(Method.GET);
var cookies = new CookieContainer();
client.CookieContainer = cookies;
IRestResponse response = client.Execute(request);
- Pros:
- Enhanced Control and Customization By using C# code, you have more control over request headers, cookies, and other parameters, allowing for fine-tuning the request as needed.
- Automated Data Retrieval C# code enables you to automate the process of downloading HTML from picnob.com, streamlining repetitive tasks and saving time.
- Integration with Existing C# Projects Leveraging C# code allows for easy integration with existing projects and applications, promoting seamless data retrieval.
- Cons:
- Complexity in Handling Cookies Implementing cookie handling in C# code might be more complex than using tools like POSTMAN, requiring meticulous handling of cookies to establish and maintain sessions.
- Risk of Server Blocking Sending multiple requests using C# code without proper headers might trigger server-side security measures, leading to IP blocking or further access restrictions.
- Conclusion: In conclusion, the “forbidden” error encountered when downloading HTML from picnob.com via C# code can be resolved effectively by enabling JavaScript and cookies in the request headers. Utilizing the outlined potential solutions, such as implementing the User-Agent header and handling cookies in the C# code, will likely lead to successful data retrieval.
