Business Logic Details

IP Address Banning Logic

The system uses a two-tier approach to IP blocking:

Automatic Detection:

The system tracks suspicious activities from each IP address
Activities flagged as suspicious include failed login attempts, invalid requests, and potential attack patterns
When an IP accumulates 10 or more suspicious activities, it is automatically added to the watch list
Automatic banning provides passive defense against automated attacks

Manual Banning:

Administrators can immediately ban any IP address regardless of suspicious activity count
Manual bans take effect instantly across the entire application
Banned IPs are blocked from accessing any system resources
Administrators can unban IPs when the threat is resolved

Email Queue Processing

The email system maintains a queue for all outgoing messages:

Queue States:

Messages enter the queue with a null sent timestamp
When delivery succeeds, the sent timestamp is recorded
Failed deliveries increment a failure counter and retain error information
Messages with errors can be edited and retried

Queue Maintenance:

Sent messages accumulate over time and should be periodically cleared
The system provides bulk deletion of successfully sent messages
Failed error notifications (system-generated alerts) can be cleared separately
Attachments are stored separately and cleaned up with their parent messages

Cache Management

The system maintains several in-memory caches for performance:

Registry Caches:

Client information
Activity rates
User permissions
Configuration settings

Cache Lifecycle:

Caches load data from the database on demand
Event-driven invalidation updates caches when source data changes
Manual cache clearing forces immediate data reload
Clearing all caches may temporarily impact performance as data is reloaded

Diagnostic Data Collection

The diagnostic system gathers comprehensive system information:

Server Information:

Machine name and IP addresses
Operating system and runtime version
Application path and configuration mode
Build type (Debug/Release)

Performance Metrics:

Process memory usage
Managed heap size
Active database connections
Response times for external services

Integration Status:

PDF service connectivity
Email server accessibility
Cloud storage connection
External API availability

Site Backup and Recovery

The system provides comprehensive site archival and restoration:

Backup Process:

Creates a complete archive of all application files, pages, scripts, and configuration
Archives are timestamped with format v2_backup_YYYYMMDDHHMMSS.zip for easy identification
The Backups folder itself is excluded to prevent recursive archiving
Optimal compression is used to minimize storage requirements while maintaining speed

Storage Options:

Backup to Cloud Storage - Creates the archive and automatically uploads it to the cloud storage Backup folder, then removes the local copy to save server space
Backup to Web Server - Creates the archive and keeps it on the local web server only, useful when cloud connectivity is unavailable or for immediate local access

Restore Process:

Requires a backup file named restore.zip in the server's Backups folder
Extracts all files from the archive, recreating the directory structure
Overwrites existing files with the backed-up versions
Preserves the archive for potential re-use

Best Practices:

Create backups before major deployments or configuration changes
Maintain multiple backups with different timestamps for rollback flexibility
Verify cloud storage backups are accessible before critical operations
Test restoration procedures periodically to ensure recovery readiness

Database Activity Tracing

The database monitor tracks Entity Framework context lifecycle:

Context Tracking:

Records when database connections are created
Tracks when connections are disposed
Identifies "leaked" connections (created but not disposed)
Logs recent database operations with timing

Diagnostic Value:

Helps identify connection pool exhaustion
Reveals inefficient data access patterns
Supports troubleshooting of performance issues
Aids in identifying memory leaks
