3131+ transformation or translation of a Source form, including but
3232+ not limited to compiled object code, generated documentation,

3939+4040+ "Derivative Works" shall mean any work, whether in Source or Object
4141+ form, that is based on (or derived from) the Work and for which the
4242+ editorial revisions, annotations, elaborations, or other modifications
4343+ represent, as a whole, an original work of authorship. For the purposes
4444+ of this License, Derivative Works shall not include works that remain

4646+ the Work and Derivative Works thereof.
4747+4848+ "Contribution" shall mean any work of authorship, including

7979+ by such Contributor that are necessarily infringed by their
8080+ Contribution(s) alone or by combination of their Contribution(s)
8181+ with the Work to which such Contribution(s) was submitted. If You
8282+ institute patent litigation against any entity (including a
8383+ cross-claim or counterclaim in a lawsuit) alleging that the Work
8484+ or a Contribution incorporated within the Work constitutes direct
8585+ or contributory patent infringement, then any patent licenses
8686+ granted to You under this License for that Work shall terminate
8787+ as of the date such litigation is filed.
8888+8989+ 4. Redistribution. You may reproduce and distribute copies of the
9090+ Work or Derivative Works thereof in any medium, with or without
9191+ modifications, and in Source or Object form, provided that You

102102+ attribution notices from the Source form of the Work,
103103+ excluding those notices that do not pertain to any part of
104104+ the Derivative Works; and
105105+106106+ (d) If the Work includes a "NOTICE" text file as part of its
107107+ distribution, then any Derivative Works that You distribute must
108108+ include a readable copy of the attribution notices contained
109109+ within such NOTICE file, excluding those notices that do not

111111+ of the following places: within a NOTICE text file distributed
112112+ as part of the Derivative Works; within the Source form or
113113+ documentation, if provided along with the Derivative Works; or,
114114+ within a display generated by the Derivative Works, if and
115115+ wherever such third-party notices normally appear. The contents
116116+ of the NOTICE file are for informational purposes only and
117117+ do not modify the License. You may add Your own attribution
118118+ notices within Derivative Works that You distribute, alongside
119119+ or as an addendum to the NOTICE text from the Work, provided
120120+ that such additional attribution notices cannot be construed
121121+ as modifying the License.
122122+123123+ You may add Your own copyright statement to Your modifications and
124124+ may provide additional or different license terms and conditions
125125+ for use, reproduction, or distribution of Your modifications, or
126126+ for any such Derivative Works as a whole, provided Your use,
127127+ reproduction, and distribution of the Work otherwise complies with
128128+ the conditions stated in this License.
129129+130130+ 5. Submission of Contributions. Unless You explicitly state otherwise,
131131+ any Contribution intentionally submitted for inclusion in the Work
132132+ by You to the Licensor shall be under the terms and conditions of
133133+ this License, without any additional terms or conditions.
134134+ Notwithstanding the above, nothing herein shall supersede or modify
135135+ the terms of any separate license agreement you may have executed
136136+ with Licensor regarding such Contributions.
137137+138138+ 6. Trademarks. This License does not grant permission to use the trade
139139+ names, trademarks, service marks, or product names of the Licensor,
140140+ except as required for reasonable and customary use in describing the
141141+ origin of the Work and reproducing the content of the NOTICE file.
142142+143143+ 7. Disclaimer of Warranty. Unless required by applicable law or
144144+ agreed to in writing, Licensor provides the Work (and each
145145+ Contributor provides its Contributions) on an "AS IS" BASIS,
146146+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147147+ implied, including, without limitation, any warranties or conditions
148148+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149149+ PARTICULAR PURPOSE. You are solely responsible for determining the
150150+ appropriateness of using or redistributing the Work and assume any
151151+ risks associated with Your exercise of permissions under this License.
152152+153153+ 8. Limitation of Liability. In no event and under no legal theory,
154154+ whether in tort (including negligence), contract, or otherwise,
155155+ unless required by applicable law (such as deliberate and grossly
156156+ negligent acts) or agreed to in writing, shall any Contributor be
157157+ liable to You for damages, including any direct, indirect, special,
158158+ incidental, or consequential damages of any character arising as a
159159+ result of this License or out of the use or inability to use the
160160+ Work (including but not limited to damages for loss of goodwill,
161161+ work stoppage, computer failure or malfunction, or any and all
162162+ other commercial damages or losses), even if such Contributor
163163+ has been advised of the possibility of such damages.
164164+165165+ 9. Accepting Warranty or Additional Liability. While redistributing
166166+ the Work or Derivative Works thereof, You may choose to offer,
167167+ and charge a fee for, acceptance of support, warranty, indemnity,
168168+ or other liability obligations and/or rights consistent with this
169169+ License. However, in accepting such obligations, You may act only
170170+ on Your own behalf and on Your sole responsibility, not on behalf
171171+ of any other Contributor, and only if You agree to indemnify,
172172+ defend, and hold each Contributor harmless for any liability
173173+ incurred by, or claims asserted against, such Contributor by reason
174174+ of your accepting any such warranty or additional liability.

···11+# Replay
22+33+This tool acts as a transparent HTTP proxy that intercepts and records all incoming and outgoing requests and responses. You can later replay these captured interactions to mock the real API without needing live network access — ideal for:
44+55+- End-to-end tests
66+- CI environments
77+- Offline development
88+- Contract testing
99+1010+
1111+1212+## ✨ Features
1313+- 🧲 Record HTTP traffic in real time
1414+- 🧪 Replay and mock previously recorded requests
1515+- 🛠️ Supports REST, GraphQL, and any HTTP-based API
1616+- 📦 Store interactions locally
1717+- ⚡ Fast and lightweight proxy implementation
1818+1919+## 🔧 Example Use Case
2020+1. Run your app through the proxy once to record real API interactions.
2121+2. Save the recorded sessions.
2222+3. Switch to mock mode for testing — no real API calls needed.
