[squid-users] Error from icap during respmod

[Arun Kumar]

 Thank you very much for the response. Are you aware of any compatible Python or Java based iCAP server implemenation? We want to implement custom virus scanning of the response. I got the book Squid: The Definitive Guide and going over for more understanding. Saw your name mentioned by the author. I am very proud to work with great people like you.

AFAICT, this ICAP RESPMOD service is buggy: It sends what looks like an 
HTTP response body chunk after sending an ICAP 100 Continue control 
message. Instead, it is supposed to send the final ICAP response headers 
and HTTP response headers _before_ sending that HTTP response body chunk.


    00:50:54.989 ... ReadNow: conn33 ... size 65535, retval 25
    ICAP/1.0 100 Continue


    00:50:54.991 ReadNow: conn33 ... size 65535, retval 137
    83
    {"activity":...}


HTH,

Alex.
