Implement File Size Limitation for AS2 Inbound Messages with Compressed Data

[vamshikrishna45]

I've set file size limits for outbound AS2 messages, but I'm facing a challenge with inbound messages due to compression. Since the data is compressed, it's hard to set an accurate size limit before decompression. Any suggestions on how to handle this efficiently?

For me, this setting from Django works - did you have issues with that ? https://docs.djangoproject.com/en/4.2/ref/settings/#data-upload-max-memory-size

I encountered an issue where I need to reject incoming AS2 messages if their size exceeds 500MB, but the file size limit should be configurable. I initially tried handling this with middleware and methods in views.py. However, due to the compression of incoming files, Django cannot determine the exact file size. Could you suggest alternative solutions for managing this?

@vamshikrishna45 : yes, the one I mentioned above. This should resolve your issue - it is standard Django functionality.

Hi,

I’m encountering an issue when retrying failed AS2 messages. Upon retry, a new Message-ID is generated for the receiver, while the sender retains the original Message-ID. This inconsistency occurs during the as2message.build() process, which seems to be causing the generation of a new Message-ID.

Is there a way to maintain the same Message-ID for both the sender and receiver during retries, ensuring that no new Message-ID is generated?

Thank you
