Template-Based Runtime Invalidation for Database-Generated Web Contents [chapter]

Chun Yi Choi, Qiong Luo
2004 Lecture Notes in Computer Science  
We propose a template based runtime invalidation approach for maintaining cache consistency of database generated web contents.  ...  In our approach, the invalidator sits between a web cache and a database server, and intercepts query statements as well as update statements transparently.  ...  We would like to thank Henry Wong from the Computer Science Department Systems Lab at HKUST for his timely technical support on the computers used in the experiments.  ...

A Survey on Web Pre-Fetching and Web Caching Techniques for Latency Optimization in Mobile Environment

2017 International Journal of Science and Research (IJSR)  
Data caching and prefetching techniques play a key role in improving the web performance in mobile information systems. Generally the mobile devices have less amount of memory storage than computers.  ...  Web traffic reduction techniques are mandatory for accessing the websites efficiently.  ...  Identical requests have identical URLs which result in the generation of the same content. The URLs of equivalent requests are syntactically different but result in generation of identical content.  ...

Consistency-preserving caching of dynamic database content

Niraj Tolia, M. Satyanarayanan
2007 Proceedings of the 16th international conference on World Wide Web - WWW '07  
With the growing use of dynamic web content generated from relational databases, traditional caching solutions for throughput and latency improvements are ineffective.  ...  Using two benchmarks representative of dynamic web sites, measurements of our prototype show that it can increase end-to-end throughput by as much as twofold for non-data intensive applications and by  ...  Even when database content remains unchanged, temporal locality of access cannot be exploited because dynamic content is not cacheable by web browsers or by intermediate caching servers such as Akamai  ...

Caching over the Entire User-to-Data Path in the Internet [chapter]

Theo Härder
2005 Lecture Notes in Computer Science  
Optimization issues in Web caches concern management of documents decomposed into templates and fragments to support dynamic Web documents with reduced network bandwidth usage and server interaction.  ...  Web caching typically supports access to single Web objects kept ready somewhere in caches up to the server, whereas database caching, applied in the remaining path to the DB data, allows declarative query  ...  Another promising area is the monitoring and recognizing of access patterns in caches and exploiting their results in prefetching schemes.  ...

PolyVaccine: Protecting Web Servers against Zero-Day, Polymorphic and Metamorphic Exploits

Luis Campo-Giralte, Ricardo Jimenez-Peris, Marta Patino-Martinez
2009 2009 28th IEEE International Symposium on Reliable Distributed Systems  
In this paper, we address precisely the topic of how to protect web servers against zero-day (new), polymorphic, and metamorphic malware embedded in data streams (requests) that target web servers.  ...  Exploits are many times used by worms to fast propagate across the full Internet being web servers one of their main targets.  ...  The first one consists in having trusted clients (e.g. web spiders that periodically traverse the web contents or well-known clients).  ...

A survey on dynamic Web content generation and delivery techniques

Jayashree Ravi, Zhifeng Yu, Weisong Shi
2009 Journal of Network and Computer Applications  
Dynamic pages require servers to generate the response content per-user request before delivering it back to the user, which introduces network traffic, server workload and results in extra latency.  ...  It first examines the dynamic characteristics of Web applications and the inherent challenges for caching.  ...  We classify them into four categories, trusted peer-to-peer Web caching and delivery, exploiting clients access patterns, considering the semantics of Web content, and correctness of caching.  ...
