Member Function Documentation

MemBuf * ErrorState::BuildContent ( void  )

Locates error page template to be used for this error and constructs the HTML page content from it.

error_directory option in squid.conf overrides translations. Custom errors are always found either in error_directory or the templates directory. Otherwise locate the Accept-Language header

If client-specific error templates are not enabled or available. fall back to the old style squid.conf settings.

const char * ErrorState::Convert ( char  token,
bool  building_deny_info_url,
bool  allowRecursion 

Map the Error page and deny_info template % codes into textual output.

Several of the codes produce blocks of non-URL compatible results. When processing the deny_info location URL they will be skipped.

tokenThe token following % which need to be converted
building_deny_info_urlPerform special deny_info actions, such as URL-encoding and token skipping. \ allowRecursion True if the codes which do recursions should converted
