Caching Proxy directives (added for 5.0.1) are missing in the ibmproxy file for Windows(R) platform
 Technote (troubleshooting)
 
Problem(Abstract)
The following directives, newly added for 5.0.1, are missing from the ibmproxy configuration file for Windows platform: ExportCacheImageTo, ImportCacheImageFrom, LimitRequestBody, LimitRequestFields, LimitRequestFieldSize.
 
Resolving the problem
The following are directives added for version 5.0.1, that are missing from the ibmproxy.conf file for Windows platform:
ExportCacheImageTo and ImportCacheImageFrom:
Use these directives only for memory cache. They help save cached objects when stopping the proxy. You can use these directives to deploy the same cache content among multiple proxies.
  • An example of the ExportCacheImageTo directive:

    #if defined (WIN32)
    # Examples: ExportCacheImageTo \\.\D:\CacheImage.0
    #else
    # Examples: ExportCacheImageTo /opt/ibm/edge/cp/CacheImage.0
    #endif

    If you enable ExportCacheImageTo, when the proxy process ends with a -TERM signal and memory cache is used, the proxy exports its memory cache contents to the specified file. You must ensure that there is enough space on the drive or partition for the file.
  • An example of the ImportCacheImageFrom directive:

    #if defined (WIN32)
    # Examples: ImportCacheImageFrom \\.\D:\CacheImage.0
    #else
    # Examples: ImportCacheImageFrom /opt/ibm/edge/cp/CacheImage.0
    #endif

    If you enable ImportCacheImageFrom, when the proxy process starts and memory cache is used the proxy imports cache content from the specified file.

LimitRequestBody, LimitRequestFields, and LimitRequestFieldSize:
These directives protect the proxy from attack.
  • LimitRequestBody size

    This directive controls the maximum body size in PUT or POST requests.
    (Default value is 10M.)

  • LimitRequestFields number

    This directive controls the number of headers sent in client requests.
    (Default value is 32.)

  • LimitRequestFieldSize size

    This directive controls the maximum header length and request line.
    (Default value is 4K bytes.)
