Currently we have only a tomcat installed and all are directly accessing the tomcat via apache, And all the webserivice calls are directly being called from tomcat and this inturn is increasing the load on the tomcat server.
Is there a way to cache these websercice calls using apache.
If so kindly provide me the details or please let me know the reasons for not being cached.
However, caching for a web service call only makes sense if the call will always return the same output for a given set of arguments/parameters and the call does not have any side effects. For example, it would be safe to cache the results of call for "return a thumbnail of the image a.png" but it would not be safe to cache the results of a call for "add a new description for part number 12345".
Also note that web service calls using the HTTP POST method may be difficult or impossible to cache.
Often, caching is used only for static content, as it can be tricky -- or inappropriate -- to correctly set up caching for dynamically generated content.
Instead of caching web service calls, you may want to analyze how Tomcat is spending its time and see if the code of your web application can be made more efficient.
