Evaluate the definite integral:

\[ \int_{0}^{1} \frac{e^x}{1 + e^{2x}} \, dx. \]

In this problem, we'll be evaluating the given definite integral from 0 to 1 of the function \(\frac{e^x}{1 + e^{2x}}\). 

### Solution Steps

1. **Simplify the Integrand**: Start by examining if any simplification or substitution can be applied to make integration easier.
  
2. **Substitution Method**: If applicable, perform a substitution to transform the integral into a simpler form.

3. **Integration**: Integrate the resulting function concerning the new variable.

4. **Reverse Substitution**: Convert back to the original variable if substitution was used.

5. **Evaluate the Definite Integral**: Apply the limits of integration to find the value of the definite integral.

### Integral Techniques
Possible techniques include substitution, integration by parts, or recognizing the integrand as a derivative of a known function.

By carefully following these steps, you can evaluate the integral accurately.
