ICAP Server - To perform content adaptation in the HTTP / HTTPS messages received from ICAP Clients. ICAP Client - To send the HTTP / HTTPS messages to ICAP Servers for content adaptation. You can configure Check Point Security Gateway as: The ICAP Client should not exceed this limit in the future. ICAP is, in essence, a lightweight protocol for executing a. The ICAP server exceeded a maximum connection limit associated with this service. The ICAP protocol is aimed at providing simple object-based content vectoring for HTTP services. This response is illegal for an OPTIONS request as implementation of OPTIONS is mandatory.īad Gateway. Error on the ICAP Server, such as "out of disk space".
ICAP Server needs encapsulated sections different from those in the request. ICAP Server timed out waiting for a request from an ICAP Client.īad composition.
In a typical scenario, an ICAP client forwards HTTP requests and responses to one or more ICAP servers for processing. Method not allowed for service (for example, RESPMOD requested for service that supports only REQMOD). The ICAP is a comprehensive, structured instrument designed to assess the status, adaptive functioning and service needs of individuals with developmental disabilities. The Internet Content Adaptation Protocol (ICAP) is a simple lightweight protocol for running the value-added transformation service on HTTP messages. These are the ICAP response codes that are different from their HTTP counterparts: In addition, see the Draft RFC - ICAP Extensions. ICAP is specified in RFC 3507 (for more information, see ( ICAP Specification). ICAP is an RFC protocol, which lets devices from different vendors communicate. Despite the similarity, ICAP is neither HTTP / HTTPS, nor an application protocol that runs over HTTP / HTTPS. ICAP is a request and response protocol that is equivalent in semantics and usage to HTTP/1.1 protocol. The adapted HTTP / HTTPS messages can be HTTP / HTTPS requests, or HTTP / HTTPS responses. The ICAP Server executes its transformation service on these HTTP / HTTPS messages and sends responses to the ICAP Client, usually with modified HTTP / HTTPS messages. The ICAP allows ICAP Clients to pass HTTP / HTTPS messages to ICAP Servers for content adaptation. ICAP is usually used to implement virus scanning and content filters in transparent HTTP proxy caches. This frees up resources and standardizes the way in which new features are implemented. The Internet Content Adaptation Protocol (ICAP) is a lightweight HTTP-like protocol (request and response protocol), which is used to extend transparent proxy servers.
