  • I do not have the answer to your question, however in general you should specify the operating system and version of the software you are using and if you have updated it to the most current version of the software. – Rowan Hawkins Aug 03 '21 at 06:06

TCP layer doesn't knows nothing about files and their sizes. It has nothing to do with it. TCP is a transport layer 4, while the files are transferred using application layer 7 (i.e. HTTP/HTTPS). So your question are quite meaningless due to this.

Besides afaik haproxy doesn't knows anything about files either. It works like a proxy and doesn't handles file uploads. It's the backend server which should worry about upload files limits. If you use HTTP(S) POST standard file uploads you should refer to your webserver documentation on how to limit HTTP(S) maximum upload size.

EDIT: also, take a look at this answer regarding haproxy doesn't handles upload limits: https://stackoverflow.com/questions/46820640/increase-the-upload-limit-of-haproxy

  • Thanks for reaching out and replying - I understand whatever is mentioned here seems to be irrelevant however i should not have use word file - basically I will say that I need to reject ongoing TCP/IP Request base on the total bytes this TCP request have received - I am able to do this using stick table but works only fine when the bytes gets accumulate like flooding. – Suketu Shah Aug 03 '21 at 16:30
