asp.net - What's the best way to cache complicated search queries in a .NET webapp? -

i have website allows users query specific recipes using various search criteria. example, can "show me recipes can create in under 30 minutes utilize chicken, garlic , pasta not olive oil."

this query sent web server on json, , deserialized searchquery object (which has various properties, arrays, etc).

the actual database query expensive, , there's lot of default search templates used quite frequently. reason, i'd start caching mutual queries. i've done little investigation various caching technologies , read plenty of other posts on subject, i'm still looking advice on way go. right now, i'm considering next options:

built in system.web.caching: provide lot of command on how many items in cache, when expire, , priority. however, cached objects keyed string, rather hashable object. not need able convert searchquery object string, hash have perfect , not produce collisions. develop own inmemory cache: i'd dictionary<searchquery, results> object persists in memory across sessions. since search results can start large, i'd want able cap how many queries cached , provide way older queries expire. fifo queue work here. i'm worried things thread safety, , wondering if writing own cache worth effort here.

i've looked other 3rd party cache providers such ncache , velocity. these both distributed cache providers , overkill need @ moment. plus, seems every cache scheme i've seen still requires objects keyed string. ideally, want holds cache in process, allows me key object's hash value, , allows me command expiration times , priorities.

i'd appreciate advice or references free , preferably open source solutions help me out here. thanks!

based on saying, recommend utilize system.web.caching , build dataaccess layer shielding rest of system. when called can create real time query or pull cached object based on business/application needs. today, memcached.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
