# ssi_with_retries - Does the server side include of a resource. |
|
# if the ssi call returns an error we'll retry it up to |
|
# the number of times requested by the caller. |
|
# If we still have a proble, no text is appended to the |
|
# output and we set some global variables. |
|
# to indicate to the caller an SSI error occured. |
|
# All of this is supposed to deal with the issues described |
|
# in LonCAPA BZ 5631 see: |
|
# http://bugs.lon-capa.org/show_bug.cgi?id=5631 |
|
# by informing the user that this happened. |
|
# |
|
# Parameters: |
|
# resource - The resource to include. This is passed directly, without |
|
# interpretation to lonnet::ssi. |
|
# form - The form hash parameters that guide the interpretation of the resource |
|
# |
|
# retries - Number of retries allowed before giving up completely. |
|
# Returns: |
|
# On success, returns the rendered resource identified by the resource parameter. |
|
# Side Effects: |
|
# The following global variables can be set: |
|
# ssi_error - If an unrecoverable error occured this becomes true. |
|
# It is up to the caller to initialize this to false |
|
# if desired. |
|
# ssi_last_error_resource - If an unrecoverable error occured, this is the value |
|
# of the resource that could not be rendered by the ssi |
|
# call. |
|
# ssi_last_error - The error string fetched from the ssi response |
|
# in the event of an error. |
